SUMMARY I was using plasma with Firefox, Dolphin and mpv running and my session crashed out of the blue. Log: https://pastebin.com/W9Fqybup Since Pipewire is mentioned, I did just update to 0.3.45 and not restated yet.

Can you check whether pipewire-media-session or wireplumber is running?
Currently it's wireplumber but before the crash it was pipewire-media-session. IIRC the crash happened sometimes after me switching from one to another and not rebooting yet, but that's more or less a guess at this point.
pipewire-media-session for me. I don't have wireplumber running.
I believe it should be wireplumber all the time for me, but i can't know if it it was pipewire-media-session for some reason before it crashed.
(In reply to Lyubomir from comment #7) > I believe it should be wireplumber all the time for me, but i can't know if > it it was pipewire-media-session for some reason before it crashed. That said, pipewire-media-session is a separate package on Arch which conflicts with wireplumber - and i don't have pipewire-media-session installed but do have wireplumber. I replaced pipewire-media-session with wireplumber at least a few weeks before the crash and had smh like 10 restarts, so definitely no chance that pipewire-media-session was running at the time of the crash.
I experienced this crash before but sadly I don't have the logs anymore. This might be related to https://bugs.kde.org/show_bug.cgi?id=450445
Can this still be reproduced after updating and rebooting? This is crashing deep into pipewire.
I don't think it has happened recently?
