All crashes are from Neon; seems like a Neon-specific bug, perhaps due to the very old PipeWire verison?
Thanks for your answer. PulseAudio is the default KDE neon sound serverr KDE. There are a few KDE PipeWire libraries installed, but no service.

Would anyone know how to reproduce this issue?
We think this is a bug in Pipewire (rather than Qt or KDE software) which Pipewire have long since fixed but happens to be triggered by a recent change in Plasma. One way forward might be to backport a newer Pipewire but the newer versions in Ubuntu don't compile easily on our Ubuntu 22.04 base. Here is one version which does compile so you could try installing that and seeing if it helps but beware it's an untested build http://embra.edinburghlinux.co.uk/~jr/tmp/pipewire-0.3.58.tar.gz

> Would anyone know how to reproduce this issue? This issue gets reproduced on my laptop. I got "Plasmashell crashed" dialog window popup every 10 minutes after I installed fresh KDE Neon OS. There appears to be no specific action that triggers the crash. The crash appears randomly when I use my system normally, like switch between Firefox, Konsole and Dolphin windows by clicking on the taskbar. Sometimes the crash popup appears precisely when I click on the taskbar. Sometimes the crash popup appears when I read a news article in Firefox and do nothing (just stare at my screen)
(In reply to hinst from comment #17) > by clicking on the taskbar. For me, 99% of all crashes of plasmashell is due to clicking on taskbar.

(In reply to Méven Car from comment #19) > https://invent.kde.org/plasma/kpipewire/-/merge_requests/163 Thank you! Will this fix be backported to 6.1.4? Or we must wait for 6.1.5?
Fix is now in
