Description:
After locking the computer for the night, even though I entered the correct password dozens of times, it would not unlock anymore and went back to the password type step in a loop. The behavior was still different than entering the wrong password (no error message), it just seems to validate it, and then go back at asking password. My session was still alive as I could still hear the audio.
When I finally chose to kill gdm, it was still failing to relog my user with a new session, and I was required to completely restart the computer.


Additional info:
* package version(s)
Version : 3.34.0-2

* config and/or log files etc.
Logs with session still opened

```

Steps to reproduce:
Sadly, no specific STR, I justed locked my session and wanted to go back at it much later.

I didn't include logs after killing gdm as I can't time those for sure and would have include huge chunks of logs, I can still do if needed, but it will be much more noisy than those for just reopening an existing session.
Oh and I don't know how severity are classified so I'll let it as is, but I guess not being able to reopen a session is in the high/critical range?
This task depends upon

I also encounter this issue when GDM is running in a tightvnc session. Downgrading GDM to 3.32.x solves the issue.
