Restart Steam

The very first thing you should try when you face the error is to relaunch your Steam desktop application.

Due to a bad update or damaged files, Steam might not be able to read the game correctly, resulting in the abovementioned error. In such scenarios, it is advised to run an integrity check for your game files. Here's how to do it:

  • Launch Steam and go to your game library.
  • Right-click on Call of Duty and select the "Properties" button.
  • Select "Installed Files" from the left panel and then click on the "Verify integrity of game files" option.

This will scan all your game files, and if anything is corrupted or missing, Steam will automatically acquire them for you.


Clear download cache
