4. Clear Platform Cache
If the error persists, clearing your platform’s cache could help. Depending on your platform, this process can vary. For consoles, turning off and unplugging your device for a minute can clear the cache. After reconnecting, power your console back on and see if the issue is resolved.
5. Verify Game Files
For PC players, verifying the integrity of your game files is a crucial troubleshooting step. If you're playing on Steam, right-click on Modern Warfare 3 in your library, select "Properties," and then choose "Installed Files" from the sidebar. From there, click on "Verify Integrity of Game Files." This process will check for any missing or corrupted files and replace them, which might resolve the error.
6. Scan and Repair
