Hello,
recently I have been experimenting with interfaces on snap I developing and have been connecting itnerface u2f-devices, when my system froze and crashed. Since then each boot freezes on startup of snapd.aparmor.service, which after around 2 minutes is killed by oom killer. Then I have about another 2 minutes in the system, before it presumably runs out of memory again and freezes.
Checking status of snapd.apparmor.service shows following
user@localhost:~$ sudo systemctl status snapd.apparmor.service
× snapd.apparmor.service - Load AppArmor profiles managed internally by snapd

When I try to do anything with my snap, I get following error:
error: snap “kiosk-app” has “connect-snap” change in progress
I cannot stop it, add or remove interface connection, remove it, nothing, everything has this error.
What can I do to recover from such situation?
Thanks
