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.
See:

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

I'm in the same boat of my friends only having a black screen. Also it seems that their audio doubles back on it's self too.

In the latest beta, the screen sharing doesn't work because it doesn't prompt the desktop environment to select the capture of the application via pipewire

The 1.8.2-beta.1 did not change how GoofCord requests screen share sources. Can you check the terminal output when attempting to screen share?

Also, does screen sharing work in a chromium based browser? You can test it here: https://www.webrtc-experiment.com/Pluginfree-Screen-Sharing

If you are talking about artifacts specifically, there is likely not much GoofCord can do, as it uses chromium's capturer with little control over it.

The screen sharing is working now, but it didn't work before, which is strange, as if the application was running in an X11 environment and made it possible to select specific windows in Discord itself.
