gdm: some times I cannot unlock screen after locking via Super+L in gnome

[antoniocorbi]

Nixpkgs version

• Stable (24.11)

Describe the bug

Using gnome desktop under wayland with automatic login enabled.
When I've got to leave my computer unattended I tend to lock screen via keyboard key-comb Super+L.
Sometimes when I type my password it unlocks the screen without problems but sometimes (even after having worked ok before in the same session) it shows a spinning circle and it can't unlock the screen.
I have to change to another tty and manually restart displaymanager.service.
I can't see anything in the logs.

Steps to reproduce

Lock the screen, sometimes it can be unlocked sometimes it can't.

Expected behaviour

Always unlock the screen.
