ok thanks after downloading the game not from steam it seems to be working. the native steam client also just crashes without any error. no idea what the issue could be...

EDIT: deleting /usr/lib/libsteam_api.so also fixed the problem for steam wtf.

as soon as I hit play, the game stays in steam on 'running' for ~0.5 seconds after which the button just returns to play. no logfile is create in the ~/.factorio folder. Running steam in console doesn't give out any errors. Starting Factorio with proton gives me the following error mesage: 0.000 202...
