COD Modern Warfare 2019 & Warzone 2020 – Fix: DEV Error

Call of Duty: Modern Warfare 2019 has finally been released on PC, and many players are encountering DEV Errors during gameplay such as 740, 1110, 5476, 5758, 5759, 5761, 5763, 6036, 6065, 6066, 6068, 6070, 6071, 6164, 6165, 6606 codes. I have listed all possible solutions for COD MW 2019 DEV errors here. These also apply to COD Warzone (Battle Royale).


Method #1

Try lowering the graphics settings and disable the Ray tracing. You can also try changing the resolution and the aspect ratio setting. Also, change the display mode in the graphics settings. And also, if you have a second monitor, you should try disabling it.


Method #2

Install/reinstall the DirectX.


Method #3

  • Run the Battle.net Desktop app.
  • Click the icon of the Call of Duty: Modern Warfare
  • Click on the Options
  • After that, click on the Scan and Repair
  • Click the “Begin Scan”

Method #4

You should disable the Crossplay in game settings.

  • Open the Options menu in the Call of Duty: Modern Warfare.
  • Go to the Account tab.
  • Set the Crossplay to Disabled.

Method #5

Turn off the OC (overclock) in Bios/UEFI and GPU software.


Method #6

Try to exit monitoring, mouse, keyboard and other background apps. MSI Afterburner, Nvidia GeForce Experience, AutoHotKey, EVGA Precision X1, RTSS Rivatuner, ASUS GPU Tweak II


Method #7

Disable the AMD Radeon Relive.

  • Go to the Radeon settings. You can find it on Windows taskbar.
  • Make sure Relive is turned off.

Method #8

You should disable the Game Bar and Game mode in Windows 10. Check out


Method #9

It’s annoying, but you need to try to uninstall and reinstall the Call of Duty: Modern Warfare.

For those getting the dreaded dev error 6328, I believe I have a solution. Try changing your color settings in the NVIDIA Control Panel under Display/Change resolution. Under option 3 “Apply the following settings”, select “Use NVIDIA color settings” and change the Output color format to RGB. This appears to have resolved this and several other game crashes I was experiencing after purchasing a new monitor (LG 38GL950G-B). I was previously running a 2k monitor at 60Hz and rarely had problems with game crashes.

16GB DDR4-3300
EVGA Black 2080 Ti

Solved! And nVidia Highligts and Overlay works after this.

I did a clean install of nVidia graphics and overlay driver 442,01 (Hotfix)
