Have attached the output of 'journalctl -b 0' after seeing this issue twice in a row.
First time, the entire desktop froze and I had to switch TTY and force kill the process.
Second time, only gnome-font-viewer froze and eventually prompted to 'force quit'
Both occurred between about 14:30 and 14:55 11-03-2022
Ubuntu 20.04.4
gnome-font-viewer 3.34.0-2
