To do so, right-click on the COD Black Ops Cold War.exe file and select Run as Administrator.

5] Update graphics drivers

Next, check if the graphics drivers installed on your PC are updated to the latest version. These can get outdated or corrupted, which could be why multiplayer is not working in COD Black Ops Cold War. Update the graphics drivers and see if the error’s fixed.

Alternatively, you can manually download and install drivers on your computer from the manufacturer’s website or use tools like NV Updater, AMD Driver Autodetect, and Intel Driver Update Utility.
