Each time I go to a sleep state or just log out, then provide my password in a login form, I get a message Unlocking failed. The password I type is correct, because after rebooting the same password works.

I am running Kubuntu with a 5.11.0-14-generic version of the kernel.
lsb_relase -a output:
Distributor ID: Ubuntu Description: Ubuntu Hirsute Hippo (development branch) Release: 21.04 Codename: hirsute
(The problem occurred before I upgraded to 21.04, so the problem isn't connected to it)
I am stuck with this problem for about a week and currently found no solution. Any help will be appreciated :)
