This does not seem to be a bug directly in GoofCord. There are many reports about the 'loop->recurse > 0' failed at ../src/pipewire/thread-loop.c:425 pw_thread_loop_wait() error online, and it seems to be caused by system misconfiguration.

You can also try a native .rpm build

Hm, strange... All packages have been installed and all services are running smoothly

Also I tried .rpm package but with no luck. When I stream, discord doesn't transmit picture and viewers can be heard on the stream, which should not be the case.

When you click the screen share button, do you first see GoofCord's screen share picker with a black "Entire screen", or your system (pipewire) screen share picker?

In screen share picker I can see my desktop on thumbnails, and after I start the stream, but viewers see only a loading screen and hear sound or they see the image with some distortions, like artifacts
