Comment 12 Mr Beedell, Roke Julian Lockhart 2025-08-06 11:15:07 UTC
Soon after log in, as I transferred some files from KDE Connect, Plasma Shell hung. When I logged out via KRunner, the DE offered to kill it so that I would be able to log out.

Comment 14 Alan 2025-08-09 16:01:51 UTC
I entered configuration mode on the panel, and it immediately become unresponsive. I didn't have access to Application Launcher as a result of this behavior, but I had Firefox running and was still able to use it.. I launched the terminal via Ctrl-Alt-T and ran `loginctl  terminate-user`. I tried to log in again switching back to Gnome Session, but it got stuck. I canceled login and restarted the computer.
