Try:
qm start 99000

If not started, so you have problem system DBus

You can try restart services:
systemctl restart dbus
systemctl restart pvedaemon pveproxy pvestatd

You can't start a template via user interfaces.

Can you make sure that you are running the latest code? There were some issues around DBus that were fixed within the last month or so, if I recall correctly.

so the template backup has been working , not sure what fixed it. could have been updates.

Also the same template has been on other pve systems all along and none of those had a backup issue.

the particular system has Debian desktop software installed . That has caused other transient issues.
