Call of Duty Modern Warfare 2019 PC version is facing errors like Dev Error 6071, Fatal Error, Dev Error 6068, high CPU usage and more. Here I have compiled a list of errors and issues that players are experiencing along with their possible fixes and workarounds.

Call of Duty Modern Warfare is a reboot that aims to revolutionize the COD franchise. With a completely revamped game engine, COD Modern Warfare features some of the best visuals of this generation.

However, the PC version of the game is facing errors and issues especially after the launch of Moder Warfare Warzone like Dev errors, 100% CPU usage and more. The following are the errors and issues that players are experiencing along with their fixes and workarounds.

Dev Errors Fix

Players are experiencing Dev Error while playing Call Of Duty Modern Warfare. These errors range are 5761, 6065, 6068, 6071 and more. These errors can be resolved by just giving the game administrative rights.

Right-click on the game’s exe file> Properties > Compatibility > check “Run this program as an administrator” and hit apply. This should resolve the Call of Duty Modern Warfare crashes.

However, this is just a generic fix and this doesn’t resolve the crashes then refer to individual fixes below.

Fatal Error Fix

Players have noted that when they try to play Call of Duty Modern Warfare they get the “Ftala Disc read error [5.0]: ‘ui.ff’”. There are a couple of fixes for this error that might work for you.

The first fix you should try is to clean boot your PC, After that, Call of Duty Modern Warfare will start running. If this doesn’t work for you then just scan and repair the game files and it should work fine.

Disk Read Error [5.0]: ‘common_mp.ff’ Fix

This is another Call of Duty Modern Warfare error that PC players are experiencing at launch. This error is most probabaly popping up for those who have overclocked their GPU.

Just revert back to GPU’s default clock speeds and disable any anti-virus program you are using. This will resolve the error.

Memory Error 01796 Fix

This is a rather strange error that Modern Warfare players are experiencing. Follow the steps below to fix this issue.

  • Update Windows, search for updates until it’s done for sure
  • Delete GPU drivers and download the latest driver updates for your GPU from the official site, don’t use Geforce Experience. Do a clean install.
  • Go to display options and run the game in full screen windowed.

Fatal error – Dev Error 6065 Fix

This is another Call of Duty Modern Warfare error that players are experiencing. However, this error is popping up due to the latest GPU drivers, just roll back to an older GPU version and the error will be resolved.

Dev Error 6071 Fix

This is another Fatal Error popping up for COD Modern Warfare players. One reason that you might be getting this error is probably due to an overclocked GPU.

If you have overclocked your GPU or own a factory overclocked GPU then revert it back to its default clock speeds and the issue should be resolved.

Dev Error 6165 Fix

This COD Modern Warfare error can be fixed by reinstalling the game and clean install your my GPU drivers. At the time of writing, there is no other workaround for this DEV Error 6165.

Crash Fix

With the launch of Modern Warfare Warzone, many players have reported random crashes while playing the game. Here is how to fix Modern Warfare Warzone crashes.

The first fix is simple. With the Warzone update, for a lot of players, Modern Warfare’s priority is set at High. Start the game and then open Task Manager > Details tab. Right-click on the Modern Warfare exe and set priority to Normal. This will fix the game’s cashing issue.

If the game is still crashing then close Blizzard client. Open Task Manager and if you see agent.exe running, terminate it. Now press “Windows + R”, type %ProgramData% and press enter. A new window will open and if you find a Blizzard Entertainment folder then just delete it. Start Battle.net and verify game files. This will resolve the crash at launch issues for you.

Dev Error 6068 Fix

According to Call of Duty Modern Warfare players, they are experiencing “Dev Error 6068 – DirectX encountered an unrecoverable error” while trying to play the game. To fix this error, make the following changes.

  • Turn off Nvidia overlay through Geforce experience
  • Set game to Windows borderless
  • Set refresh rate and FPS limit to match my monitors
  • Made sure you have latest Windows Update
  • Turn off GPU overclock and reverted back to stock clocks
  • Turn off XBOX Game Bar
  • Turn off RTX
  • Turned off MSI Afterburner and all other overlay apps
  • Set game to HIGH CPU PRIORITY on Task Manager
  • Set particles setting to Low

If you don’t like reducing the game’s settings then you can potentially resolve this issue by locking Call of Duty Modern Warfare at 30 FPS. Open Nvidia Control panel > Manage 3D Settings > Program Settings.

Select the game from the list and set vertical sync to “Adaptive Half Refresh Rate”. Apply the change, start the game and disable Vertical sync in-game and the game will be locked at 30 FPS. This will reduce the CPU and GPU usage resulting in stable performance.

Crash At Launch Fix

According to Players, when they start Call of duty Modern Warfare it just crashes at launch or doesn’t launch without any error. Here are a few fixes that might help you.

One reason for the game to crash at launch could be your anti-virus software or Windows Defender detecting the game’s exe as Trojan. Either disable your anti-virus software or make an exception for COD MW exe in your anti-virus software and the issue will be resolved.

If this doesn’t work for you, then the culprit might be third-party monitoring software like MSI Afterburner or GeForce Experience. Disable these and the game should work fine.

However, if you were using MSI Afterburner and disabling it hasn’t solved the issue then follow the steps below.

  • Open RivaTuner Statistics Server(RTSS).
  • Click the Add button and navigate to the game’s folder.
  • Add Call of Duty Modern Warfare’s exe under Application profile properties.
  • Set Application detection level to None for the game application.
  • Close RivaTuner Statistics Server.

100% CPU Usage Fix

To fix 100% CPU usage for COD Modern Warfare, go to “C:\Users\ YOUR NAME \Documents\Call of Duty Modern Warfare\players”.

Here you need to edit two files namely config.cfg and config-C7XXXXXX.cfg. Open these files and look for “setcl 895653276”. Now check that the resolution in front of this line is the same as your monitor’s display resolution.

If it’s set to a high resolution then change it to your monitor’s native resolution. Save it and run the game and the 100% CPU usage will be resolved.

If the set resolution is the same as your monitor’s native resolution, then you can try locking the game at 30 FPS to reduce the CPU usage. Open Nvidia Control panel > Manage 3D Settings > Program Settings.

Select the game from the list and set vertical sync to “Adaptive Half Refresh-Rate”. Apply the change, start the game and disable Vertical sync in-game and the game will be locked at 30 FPS.

Reportedly, COD Modern Warfare 2019 sets its priority to high by default which causes the CPU usage to increase. One potential fix for this is that start the game and then open Task Manager > Details tab. Right-click on the game’s process and set priority to “Normal”.

That is all for our Call of Duty Modern Warfare fixes for errors like Dev errors, crash at launch, Fatal Error, Dev Error 6071 and more.

The disc read error is a small but annoying issue that can sometimes show up out of the blue, preventing you from playing Call of Duty: Modern Warfare. Luckily, the error is very easy to fix.

It’s safe to say that Call of Duty: Modern Warfare is a breath of fresh air for the franchise with the return of the singleplayer campaign and its traditionally excellent multiplayer. Infinity Ward and Activision really knocked it out of the park with the latest instalment but as expected, no game is perfect and issues will surface from time to time.

One minor issue that can be quite annoying occurs during the game’s first loading screen. The error message that pops up is not the same for everyone but luckily the fix for it works in most of the cases. If you encounter disc read error message, followed by the name of the map like safehouse_main_tf.ff or  ‘ui.ff’ common_mp.ff, there are few things you can try to fix this:

RUN THE GAME IN SAFE MODE

This one is pretty obvious and every time when Call of Duty: Modern Warfare quits unexpectedly, you should use the safe mode, which basically starts the game on the lowest possible settings but keeps your controls intact.

SCAN AND REPAIR THE GAME FILES

If the safe mode is not working, the second solution for this issue is once again, pretty simple. All you have to do is scan and repair Call of Duty: Modern Warfare game files in Battle.net launcher. Here’s how you’ll do that:

  1. Run Battle.net
  2. Click on Call of Duty: Modern Warfare under Partner Games
  3. Click on the Options menu right below the game’s logo.
  4. Choose Scan and Repair and then Begin Scan

This will scan the game files and if any files are missing, the launcher will automatically download it to repair your game.​​​

RETURN YOUR GPU TO STOCK CLOCKS

If you overclocked your graphics card, try returning it to stock clocks. This fix comes directly from Activision who suggest that reverting back to defaults can solve the problem.

DISABLE YOUR ANTIVIRUS SOFTWARE

If none of the above works, try disabling your antivirus software and run both Battle.net launcher and ModernWarfare.exe as administrator. ModernWarfare.exe can be found in the game’s installation folder. (Options > Show in Explorer)
