QJackctl and Ardour Mint 21 - not working

Hello, i don’t know, how i setup right for Ardour.
Ardour crashes or brings error if switch to Jack. Can’t find an actual tutorial - only very old things with other interface.

Can anyone help me?

Is Mint 21 running pipewire by default? Are you using native jack or pipewire jack. A wild guess but it could be related to pipewire.

Hello, i found the solution.
