Certainly looks stuck, but unclear why. I was afraid something like this could happen (or someone could have the ntp servers blocked on their firewall), which is why I started building out the UI for it. In older versions the DVR server would never start until time sync was achieved.
Maybe check find /run/systemd/timesync -ls
Then try systemctl restart systemd-timesyncd
and see if that makes systemctl list-jobs
list go away and get things started up.
