Whenever I try to launch a game through Proton it immediately crashes. Steam dialogue for launching the game works fine, but as soon as the game itself should launch it crashes. This seems to effect every version of proton. I have tried deleting the files for proton and re-installing them and re-installing steam, but the problem persists.
GTX 1060 6GB with up to date non-free drivers.
I don’t know where to start debugging this - is there a way to get logs from steam? Is there a way to install steam from scratch without preserving any old config/files?
Proton works fine on my laptop which is a practically identical configuration, although obviously very different hardware. (no discrete GPU)
