If you're using a Xorg session (the default one named "Ubuntu") then the
mouse pointer is moved by xorg-server independently of gnome-shell. This
means that if the mouse pointer is frozen then it's either Xorg or the
kernel that's freezing.
If you're using Wayland and not using a Xorg session then please try
using the latter.
Can you please reproduce the problem again, recover using the lid trick
and then without rebooting run:
dmesg > dmesg.txt
journalctl > cur_boot.txt
If you need to reboot to recover then instead please run this
immediately after rebooting:
journalctl -b-1 > prev_boot.txt
and send us the resulting text file(s).
