"akonadictl fsck" hung, dbus inspection fails on the background

cross posting upstream bug: https://bugs.kde.org/show_bug.cgi?id=427262

I am running akonadi 20.08.1 on Kubuntu 20.10 (akonadi server build from source code, but package version behaves the same). When I want to run "akonadictl fsck" this tool hung. When I run "dbus-monitor --session" meanwhile, I see these errors:

When I run akonadi-server from different location (during debugging), fsck process correctly. So, it is possible that Apparmor rules are involved.

Is here some Apparmor master that would help me fix D-Bus rules?
