HA does not start after a backup restore

Before updating HA (HASSIO) I made the backup (full). The update knocked out the CTAPO integration. So I decided to go back. I have restored the backup from the GUI. HA has disconnected but the GUI no longer starts.
I can connect via ssh. I also tried the resume from CLI, but nothing.
Do I have to do it all again?
Any ideas or suggestions?
