Rocko,
Sorry to hear about this problem. However with a large number of open
bugs with similar symptoms we can't pin down the exact cause of this one
without more information.
If you can then please try logging into the machine remotely (e.g. via
SSH), and run 'journalctl -f' before reproducing the bug. Do you see any
log messages that are helpful? How about from 'dmesg'?
Also while logged in remotely, after reproducing the problem please
check if the gnome-shell process is still running. And if so then please
run 'kill -ABRT' on it to generate a crash file which you can later
upload with 'ubuntu-bug' or 'apport-cli'.

Title:
gnome-shell freezes after resume then unlock
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
Often after resuming and then entering my password to unlock gnome-
shell, when I press the enter key gnome-shell immediately freezes. The
lock screen is still displayed, the mouse no longer responds, and the
keys no longer respond (I can't even get a tty console with CTRL-ALT-
Fn key). I have to perform a hard reset at this point because gnome-
shell remains frozen even after leaving the PC alone for 15 minutes.
I haven't been able to find any crash files or error logs.
It seems that this freeze is much more likely to occur if I have
changed location between suspending and resuming and am therefore
connecting to a different wifi router. Once, however, it happened at
home on the same router and I was able to log in via ssh from another
machine (so only gnome-shell was frozen, not the kernel). However, I
couldn't see any messages or reason that gnome-shell had crashed, so
all I could do was reboot (any hints as to what I should try at this
stage are welcome).
Bug #1709994 looks similar but in that case a) the user is using Xorg,
not Wayland, b) he also gets past the lock screen, and c) gnome-shell
eventually restarts.
