Is it the same issue like the initial comment? I.e.
'GDBus.Error:org.freedesktop.machine1.NoMachineForPID:'?
What process does the offending PID refer to (is it the PID 1 of the
container?)
Can you check what's in /proc/$PID/cgroup (when the error occurs)?

FTR, openSUSE TW defaults to the unified (v2) hierarchy now and it's not
affected (was confirmed in comment 4).
