HA 2021.9.1 - Cannot Delete Backups

I am running Home Assistant OS, with latest Core (2021.9.1), and cannot delete older snapshots/backups.

I get the following error in my Logs:

2021-09-03 16:08:47 ERROR (MainThread) [homeassistant.components.hassio] Failed to to call /backups/adbc14ab/remove -

An issue has been raised and a fix will be in the next release.
