Reproduction

I'm having the same issue. It seems that the wine prefix in the compatdata folder isn't being created on launch (the folder is empty except for a single 0 byte pfx.lock file) and so the game just fails to open. The thing is, (for me at least) when you run Steam in a terminal it starts working properly. Once you close the terminal though, it stops working again.

I'm having the same issue too.
