Modern Warfare 2 Dev Error 11557 Workaround:

Here’s the workaround from Infinity Ward:

Players repeatedly encountering Dev Error 11557 message may have a corrupted file, which should be addressed by reinstalling the game.

If the issue persists, the corrupted file could be in the streamer cache.

Go to SETTING ➡️ GRAPHICS ➡️ QUALITY ➡️ On-Demand Texture Streaming ➡️ Show More ➡️

and set allocated texture cache size to the minimum.

That seems to do the trick for most players. Mind, this doesn’t prevent other crashes from happening, but this should help. For more on Modern Warfare 2 and Call of Duty content, make sure to bookmark our COD game hub!
