RPCS3 Crash on Fedora 36 start up

Hi all,

After a fresh install of Fedora 36, when starting up the appImage for RPCS3, latest version, I get a Segfault pop up. I am pasting here the log and gdb output, since they are quite small. It happens both on an X11 and a Wayland session. It looks like an issue with pipewire...

Code:

Thanks for your help!

Can't reproduce on Manjaro Linux 21.2.6
Maybe you can start by trying 0.0.21-13478 on https://rpcs3.net/builds

Hi Ani,

Just tried with same verison. Same problem, sadly. I've also deleted the .cache and .config folders, no change.
