Reinstall your GPU drivers
It’s time to manually reinstall GPU drivers if there might be some issue with the driver files themselves.
Step 1: Right-click Start and select Device Manager from the menu.
Step 2: Under Display Adaptors, find your graphics card’s name, right-click on it and click on Update Drivers.
Step 3: Click on Search automatically for drivers. Windows will then automatically look for and download the latest drivers for your particular GPU.
While this should help resolve the error, in case it doesn’t, click Uninstall device and restart your PC to force Windows to install the required drivers. You can then update them later.
Chances are there could be an issue with your Windows installation that might’ve been fixed in the latest update. Update Windows to the latest update possible and try running the game again.
Change your loadout
The error can also be caused by a glitch inside the game in one of your loadout items. If you’re using any loadouts or operators from Black Ops Cold War, try changing them back to their Modern Warfare counterparts and try again. You can also try removing all your skins.
Try another account
If nothing else works, try using another account to play the game to see if that resolves the error. You can sometimes run into the dev 6634 error as it can be limited to specific accounts.
