1. Repair or Verify Integrity of Modern Warfare 2 Files (PC)

PC players can easily repair missing or broken game files through the Steam or Battle.net launchers.

Here’s how you can repair the game files through Steam:

Go to the Library.
Select COD: Modern Warfare 2.
Click the gear icon (Manage menu) on the right-hand side of your screen. Or right-click COD: Modern Warfare 2 from your games list.
Pick Local Files.
Choose Verify integrity of game files… menu.

And here’s how you can repair the game files through Battle.net:

Open the Battle.net desktop application.
Click on the COD: Modern Warfare 2 icon.
Click the gear icon next to the Play button, and choose the Scan and repair option.
You’ll need to reinstall the game if there are any missing or corrupted files.

2. Delete and Reinstall Modern Warfare 2 (Console)

Unfortunately, console players on Xbox One, Xbox Series X, PS5, or PS4 don’t have another choice but to completely delete and reinstall the whole COD Modern Warfare 2 game in order to fix the Dev Error 11152 message. A clean installation with the latest update should ensure that the game no longer has corrupted files and that all the necessary files are installed.

3. Change the Language to Arabic

However, Reddit user Plenty-Ad-7693 claimed that changing the game’s language to Arabic — for some reason — can temporarily fix the problem. According to Plenty-Ad-7693, you should try playing the game in Arabic for a while, a mission until you get to a checkpoint, then change the language back to English.
