Hmm so you had to delete a file from the last patch to get it to run on Linux? I definitely didn’t have to do anything like that, running proton experimental through Steam. Curious, but what distro are you on?
I’m on an Arch based distro called Garuda.
This is where I found the fix.

Got to love that site. Always good to know that I’m not alone in my random errors.
