EOS with the recent updates, KDE Plasma 5.27.9. A few times a week I find my open app windows closing without any complains: all windows one by one, in a few seconds, including KDE task bar, so it’s just bare desktop left on the screen. I can go TTY (ctrl-alt-f3), go root and reboot.
How can I diagnose this and fix that?
ps: not too experienced with Linux, sorry
