I can see launcher and hit play but then nothing happens, It just stays on launcher. I tried --skip-launcher option and other Proton versions but none of them have worked. I'm on amd gpu and Proton-GE sometimes throws and error of "failed to collect displays" message, any idea?

SOLVED:

apparently sway was the problem and fixed it with below startup command

echo env --unset=SDL_VIDEODRIVER mangohud "%command%
