Help running AppImage

Plex Labs
1

Player Version#: 3.4.0
OS: Fedora 33, Gnome 3.38

I placed the appimage in ~/.local/bin/ and tried to launch it from terminal.
I noticed that Plexamp was able to automatically download 3.4.0 and update itself (thus changing the path to ~/.local/bin/Plexamp-3.4.0.AppImage.

When I ran this the first time, I saw the loginscreen and logged in to find only a gray screen. This occurs on both 3.3.x and 3.4.0.

I think Fedora may be a hard target for an AppImage because it uses PipeWire/Wayland, and PlexAmp may not be able to speak to PipeWire via the PulseAudio api.

This is where output stops.

I know Electron.js has added Wayland native support only recently, but I expected it to launch in an xwayland context at least.

Is there anything this output can hint to helping get PlexAmp to run on my machine?

I’m seeing these logs as well, running cinnamon on X. My behavior is different though, the app never launches.
