L4D2 Crashing to Desktop WITHOUT Error

[A Whimsical Statue]

The game only does it when I'm playing certain custom maps. Of course I then and go unistall the custom map, but it shoudln't do that. If I want to play a custom map I should be able to. Any possible solutions? I've tried the CSC folder, reinstalling the game, verifying game cache, cleaning out addons folder, setting higher RAM for the game, etc.

You probably have a conflicting VPK, bad map, or you need to verify your game cache.

I have verified my game cache, plenty of times. It might be the map, but multiple maps have done it.
