Hello Fulvio,
have you possibly kdeconnect installed and those notification, as far as
they are still readable, are related to a connected Android phone?

Then this upstream issue might be related:
  https://bugs.kde.org/show_bug.cgi?id=442645


I ask because I have kdeconnect installed and see all some
days such a hang you are describing.
(But I don't get a call like in above upstream bug, it is just notifications.)


I am able to "free" my session by this sequence from SSH or virtual terminal session:
  killall plasmashell
  killall kwin_x11
  export DISPLAY=:0
  plasmashell --replace &
  kwin_x11 --replace &

(But unfortunately that environment is not exactly the
same so a restart of the session might be still a good idea,
or repeat from a still running konsole window with a good environment ...)


I generated a core file via gdb last time for both processes,
but when I inspected it now I did not see an obvious interesting thread...


Kind regards,
Bernhard
