Restoring partial backups

My HA instance is crashing after a recent update. I would like to restore from the last partial backup of Core_2024.1.6. However if I try ‘ha backups restore slug-id’ the systems says Error partial backup. I don’t have ssh access so I can’t move files around. How can I get this system restored to a working state? (HAOS is running in a Virtualbox VM).

I managed to get it working again with the ‘supervisor repair’ and the 'core update --version=Core_2024.1.6 commands. Still not sure what the problem was.
