I ran into this on the 10th, had to open a vty and run `gsettings set
org.gnome.desktop.lockdown disable-lock-screen true` to get back in.
after installing updates that evening, and setting the previous setting
to `false`, and restarting (to apply updates to gnome-shell
(3.36.1-4ubuntu1)) this was no longer an issue.

Starting today, gnome-shell is crashing when you try to unlock the
