Why is here an Category for Mobile App but not for the Desktop App?

[totow93]

also for the Issues why should I fill out how my Music Assistant run, when I only have an problem with the Desktop App?

The only UI that works is the right click menu on the Tray icon, the windows are just plain white.

I just download Music.Assistant_0.3.4_amd64.AppImage an my System with Linux (CachyOS).
When I start it with the Terminal I get:

Could not create default EGL display: EGL_BAD_PARAMETER. Aborting...
