App Does Not Launch From Steam

[john-okeefe]

I've installed the AppImage to my Steam Deck and added it as a non Steam game. It will not launch either in Desktop (X11) mode or Game (Wayland) mode. For Wayland I even tried adding the --enable-features=UseOzonePlatform --ozone-platform=wayland flags.

I also tried this on my Arch laptop with the app image and aur versions. Nada.
