This sounds suspicious:

Separately, you seem to have a number of extensions installed:
'remmina-search-provi...@alexmurray.github.com'
'alt-tab-worksp...@kwalo.net'
'openweather-extens...@jenslody.de'
'un...@hardpixel.eu'
'gsconn...@andyholmes.github.io'
'cpuf...@zdyb.tk'
'cpufreq@konkor'
'cpupo...@mko-sl.de'
'drive-m...@gnome-shell-extensions.gcampax.github.com'
Although I mostly suspect the last one, please uninstall all of them and
see if that solves the problem. You will need to uninstall them all and
not just disable them because extensions can still interfere when
installed and disabled. We need to do this because so many bugs are
caused by extensions. Eliminating them very often solves the problem.

Title:
gnome-shell hardlocks under load
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
With the upgrade to eoan, my GNOME and Ubuntu sessions started locking
up hard when under load (i.e. when I start my session and start a
bunch of applications).
I couldn't find anything special in gdb, whether it's stuck or not,
the stack looks mostly the same:
