Below, I have thoroughly discussed all these steps to help you get rid of this error 11557 PS4, PS5, Xbox, and PC once and for all.
Here are the methods to fix dev error 11557 in COD MW2:
1. Reinstall Modern Warfare 2
Uninstalling and reinstalling a 150GB game can sound off-putting to some users. But this guideline came directly from the developers since it’s the best way to resolve any corrupted game files.
Here’s how to reinstall Modern Warfare 2 on your PlayStation console:
- Head over to the game library of your PS4/PS5 and find Call of Duty Modern Warfare 2 from the game list.
- Press the Options button on your PlayStation controller and select Delete > OK.
- Go to the PlayStation Store from your console and download the game again. If you have a physical copy, insert the Disc and complete the setup process.
- Launch the game and try to enter a match.
For PC, open the Battle.net or Steam launcher and uninstall the game from there. Additionally, if you’re using an Xbox, go to your Game Library, select COD MW2 & press the menu button on your controller. Then select Uninstall > Uninstall all. Then install it again from Microsoft Store.
If you still see the same error code, then the console/PC might be having some other issues. In this case, move on to the next method.
2. Reduce Texture Streaming
As Infinity Ward suggested, if reinstalling the game doesn’t fix the issue, consider tweaking the texture streaming settings from the in-game graphics option. This can deviate texture streaming load from the PC/console hardware and resolve any streamer cache related problems.
Follow these steps to reduce texture streaming on COD MW2:
- Launch the game and go to Settings > Graphics. If you’re using a PC, select the Quality tab.
- Click on Show More below the On-Demand Texture Streaming option.
- Select the Allocated Texture Cache Size option and set it to Small.
That’s it. Now save the changes and reboot the game. You should be able to play MW2 without facing the dev error again. This method works for both PlayStation and Xbox consoles.

4. Reset Your Console
If none of the above methods have worked for you, then hard reset your console as a last resort to fix this problem. Here’s how:
To Reset PS4
- Go to the Settings from the homepage.
- Scroll all the way down to Initialization and select it.
- Click on Initialize PS4.
- Select Full.

- Hit Yes.
To Reset Xbox
- Press the Xbox button on the controller.
