Thanks. Your system log is full of error messages about 'extensions'
that I have never seen before. Like:
févr. 20 11:55:15 hostname nautilus[2460]: Unexpected plugin response. This
probably indicates a bug in a Nautilus extension: handle=0x55d6331da690
févr. 20 11:55:15 hostname nautilus[2460]: Unexpected plugin response. This
probably indicates a bug in a Nautilus extension: handle=0x55d6334b7770
févr. 20 11:55:15 hostname nautilus[2460]: Unexpected plugin response. This
probably indicates a bug in a Nautilus extension: handle=0x55d63425e160
and
févr. 20 12:43:51 hostname gnome-shell[2029]: JS ERROR: ReferenceError:
NM80211ApFlags is not defined
WirelessList<._getApSecurityType@/home/username/.local/share/gnome-shell/extensions/extend-panel-menu@julio641742/indicators/network.js:448:1

WirelessList<._accessPointAdded@/home/username/.local/share/gnome-shell/extensions/extend-panel-menu@julio641742/indicators/network.js:567:27
Please try disabling/uninstalling all gnome-shell extensions other than
the Ubuntu default ones (gnome-shell-extension-appindicator, gnome-
shell-extension-ubuntu-dock), and tell us if the bug persists. If that
fixes it then please try to figure out which extension was causing the
bug, by reintroducing them one-by-one.

Title:
gnome-shell freeze on key press while high CPU load
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
This bug happens randomly (once an hour), on keyboard input in
different apps, ex Firefox address bar, Alfred launcher or Gnome
Overview.
I could not find steps to reproduce (tried reducing keyboard interval
and repeated keypress following STRs from #1731420 but it did not
freeze, though CPU use increased).
System is completely frozen, cannot switch to TTY, but music continues
to play. Sometimes it logs out but most of the time I have to force
reboot by long pressing the shutdown key.
syslog show message : "Key repeat discarded, Wayland compositor
doesn't seem to be processing events fast enough!" multiple times.
Looks similar to bug https://bugzilla.gnome.org/show_bug.cgi?id=777693
