Backup issues after upgrade to 2022.2.x

since the update to 2022.2.x version, backup is not working anymore.
Here are my logs:
Logger: homeassistant.components.hassio Source: components/hassio/ Integration: Home Assistant Supervisor ([documentation](, [issues]( First occurred: 13:17:10 (1 occurrences) Last logged: 13:17:10
Failed to to call /backups/new/full - Unknown error, see supervisor

BTW, the automation does not work either…

Any idea?
