Stuck in a loop when restoring backup

[rdeherder]

Describe the bug
When restoring a backup Medusa gets stuck in a loop with 2 exceptions.
The backup was made from the Medusa app on a Synology nas, version 1.0.22. The backup was loaded into a Medusa docker image from LinuxServer, version 1.0.22.

To Reproduce
Create a backup from a Medusa version 1.0.22 on a Synology nas. Restore the backup file into a newly created Medusa docker container version 1.0.22 on a QNAP nas.

Expected behavior
The backup should be restored correctly.
