Steam Proton Games won't launch

@megavolt Here’s the output from both commands. Since even tty does not work, I retrieved the information from the system via manjaro-changeroot -a from a live USB:

I did some experiments with other kernel versions. It seems the legacy driver is the only one working for all of them. At one point I deleted all contents in /etc/X11/xorg.conf.d/ and reinstalled the latest driver, but that didn’t help, either.

I even flashed a new image to the live USB (formerly Manjaro 21.0.6, now 21.0.7) and tried again booting from the stick with the proprietary drivers → no improvement though. I guess until further notice, I’m stuck with the legacy driver.
