Cannot start via flatpak (Fedora 42, Gnome 48, Wayland)

[arpadgabor]

I'm on Fedora 42 with Gnome 48 and Wayland. For a while now (even before upgrading to 42) I've been getting this error when trying to run the app:

❯ flatpak run com.mastermindzh.tidal-hifi

Wayland socket is available, running natively on Wayland.
To disable, remove the --socket=wayland permission.
Using NVIDIA on Wayland, applying workaround

I'm not sure what might be causing it, because dbus is running:

❯ systemctl status dbus

and the file exists:

I have the latest available Nvidia drivers installed if that helps.

I've also tried uninstallign & reinstalling the app, updated packages, rebooted a number of times, restarting the dbus service, and tried finding similar problems online but there was absolutely no solution and now I'm stuck. Any idea what might cause this? I'd like to avoid reinstalling my system...

Please let me know if I can provide any other diagnostics that might be useful to debug this.

This is a general issue with Electron, NVIDIA and Wayland. Heroic also has a longstanding Issue open where people kept discussing this issue and their only way to get it to work was by forcing the flatpak to start in X11 mode
