@ataxyanetwork I managed to install XOA (Current version: 6.2.2 - XOA build: 20251219) and did some more testing.
I am experiencing the same issue when trying to restore from an existing backup.
When I create a new backup job, I can perform a filelevel restore without any problems. However, when I rerun the job, I am no longer able to restore from the most recent backup. It only works with the initial backup.
Can you also reproduce this ?
