Here is what you should do:

1. Press   Windows + I   to open   Windows Settings  .

Check Modern Warfare 2 server status

You may encounter #x41 error in Modern Warfare 2 due to a server issue. You can check the status of the server by visiting the Activision Support Twitter page or the Infinity Ward Twitter page.

Reinstall Modern Warfare 2

If none of these other methods worked, the only way to fix the problem might be to reinstall Modern Warfare 2. Just make sure you delete Call of Duty game files and folders before reinstalling it.

This method will take the most time as you will need to wait for the entire game to be reinstalled before you can see if it worked. However, if there is a problem with any of your game files, this might fix it.
