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/websocket_api.py:120 Integration: Home Assistant Supervisor ([documentation](https://www.home-assistant.io/integrations/hassio), [issues](https://github.com/home-assistant/home-assistant/issues?q=is%3Aissue+is%3Aopen+label%3A%22integration%3A+hassio%22)) 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?
Thanks
Vic
