To address this, use your game platform's verification feature. On platforms like Steam, right-click the game, select "Properties," navigate to the "Local Files" tab, and click "Verify Integrity of Game Files." This process automatically scans and repairs corrupted or missing files, ensuring the game can launch properly.

Method 3: Update System and Drivers

Outdated or corrupted system files and drivers can also contribute to COD 21 errors and crashes. Regularly updating your system and drivers is crucial for stable gameplay.
