Thanks for the bug report and for taking the time to make a video. It appears the gnome-shell process is frozen (likely crashed). The mouse cursor works still because it's managed by the Xorg process.
Next time the problem happens, please: 1. Wait 10 seconds. 2. Reboot. 3. Run: journalctl -b-1 > prevboot.txt 4. Attach the resulting text file here. 5.
