Tumbleweed only start in emergency mode.

I’m having this issue on a long running stable tubleweed after upgrading, today, via zypper dup

from the journalctl in emergency mode

systemd: dev-system-home.device: Job dev-system-home.device.start timed out

end of the logs have a “Dependency failed for home” before getting emergency console (likely due to the above).

Earlier, there is another error I don’t know if its related to failure to mount home, (including in the event its not a red herring).

systemd-udev: Specified group 'plugdev' unknown

I can’t use snapper to roll back because I get the following error from the emergency console

snapper list
Failure (dbus fatal exception)

Any suggestions advice to get the system back up and running is appreciated. Thanks
