Lutris can't use Proton anymore

I was wondering why UMU stopped working on Lutris v0.5.17 (which mine is installed as a “.deb” file) recently and that was the problem.

while I did mine through the file manager it has the same effect as what you mentioned from terminal as once I made that “umu_run.py” executable it now seems to work as expected once again.

because something must have gotten a bit out of whack as not long ago it was fine. so I assume when they updated to v1.1.3 is when the issue started as it was not executable(?).

Newer version does not allow proton to work, got this issue and i can’t fix it with the same command
