Since the recent update to 5.18, Alien:Isolation crashes to desktop after some seconds in the game. The console output of steam just says there is a segmentation fault.
When I start a snapshot with 5.17.5, I can play it without interruption. I don’t know whether this affects other Feral games; A:I is the only one I have at this time.
I’ve recently been playing this masterpiece on Steam Proton, and I’ve suggested an updated configuration here - https://www.protondb.com/app/214490 - Proton 8.0-4 is recommended instead of Experimental, especially if you want to use some (beautiful) mods. Unfortunately, the native version won’t support them because they used to be in .exe format (they work in your system with Wine as base).
