ge-proton AppImage Unhandled exception in gamescope (Steam Deck Gaming Mode)

[TheGrizzMD]

I have an application that works on Steam Deck desktop mode (X11), but encounters an error when running the same command within gamescope (Steam Deck gaming mode). I think gamescope uses Xwayland. Here is the backtrace:

The same application is working with the official proton-ge release in gamescope/gaming mode as well, so the issue seems to be unique to the AppImage. I am using wine-staging_ge-proton_8-26-LoL-x86_64.AppImage

wine-staging_ge-proton_8-26-LoL-x86_64.AppImage also appears to be a build that was specifically made for League of Legends, is there a way to access one of the earlier builds of wine-ge-custom?

ah thats wrong build my bad didn't checked ge builds, can you download again,

since LoL builds were only meant for leagueoflegends.

Thanks! I tried the new build and still get an unhandled exception when running in gamescope/gaming mode on steam deck, so it must be some other cause.
