Portal 2 constant co-op crash?

[Goobston]

Everytime a friend and myself try to play a game it crashes after about 2 minutes of play time. No idea why, help?

For me it crashes when it says "Search for Co-Op partner".I really hope there is aq fix to this

I am getting this issue too, first time back to portal 2 in awhile, and first time playing coop. again, not sure why.

Crashes for me on most levels now. Only recently started .Mostly when picking up block or portaling. sometimes just happens randomly !

there is probably a problem with Steam thats why the game crashed

I'm having this problem, where Portal 2 crashes when "searching" for a co-op friend. Is there a fix?
