It seems everything started to fail after resume because the X server went away:
Okt 25 05:43:31 GS1 gnome-shell[1346]: gnome-shell: Fatal IO error 0 (Success) on X server :0.
However Xorg did not crash. It just decided to shut down on system resume:
Okt 25 05:43:31 GS1 /usr/lib/gdm3/gdm-x-session[1302]: (II) Server terminated successfully (0). Closing log file.
I don't know why Xorg would decide to shut down on resume. Maybe it was a delayed reaction to using the power button? If you use the power button in a normal Linux console then indeed the normal behaviour is to shut down.
Maybe the problem was that gnome-shell misinterpreted "Fatal IO error 0 (Success)" which then started the shutdown.
