Had a similar problem on Pop_OS. Seemed to be an nvidia diver issue. Suspend would stop working after a driver update and sometimes go away after another update. This happened 2 or 3 times. There were also some logs about nvidia suspend issues. My troubleshooting was unsuccessful and iirc, it was complicated to keep pop from updating so I eventually swapped nvidia for amd and it stopped being an issue.
