Hello,

When I lock my computer, the following shows up on a black screen:

The screen locker is broken and unlocking is not possible anymore.
In order to unlock switch to a virtual terminal (e.g. Ctrl+Alt+F2), log in and execute the command:

loginctl unlock-session 3

Then log out of the virtual session by pressing Ctrl+D, and switch back to the running session (Ctrl+Alt+F1)

I'm able to switch back to the running session with no problems by following the written instructions, however, I do not know how to solve this problem completely.

In journalctl, I think I have found the source of the problem, but I couldn't figure out how to solve it:
