Not opening on Fedora Workstation 44

Just upgraded to Fedora Workstation 44 and Datcord does no longer open.

When I click the icon it does not open a window and I get a crash notification after a few seconds. It shows under background tasks though. And I can hear discord sounds etc.

If I try to run it from the cli I get this:

```
user@host ~> flatpak run io.github.gamingdoom.Datcord
This instance is first.
[9] Sandbox: CanCreateUserNamespace() clone() failure: EPERM
[GFX1-]: (gnome) Wayland protocol error: interface 'wp_image_description_v1' has no event 2

Window -> Headless

Tried to delete the cache folder (``/home/user/.var/app/io.github.gamingdoom.Datcord/cache``) but that didn't work either.
