Jack not working after upgrade to 22.04.1

[kalpana]

So as the title says, after upgrading jack doesn't want to work anymore.

Already tried to purge/remove all config and all jack-related packages and reinstalling them, didn't help. Tried googling around and there were comments about adding audio group permissions and such but so far no luck.

Whenever I try to start jack through Qjackctl I get these messages:

If I try to run jackd from terminal, I get:

And with jackdbus:
