Garbage collection failed

[iammarxg]

Hi. When I type "backup gc" it says garbage collection failed. It doesn't delete the backups.

I have tried running "backup prune" as well and it prunes the images successfully, but doesn't delete (as it says in the docs).

This is a major issue since it corrupted my latest backup and my world because my SSD ran out of storage, so I had to go back to an hour old backup (my backups happen every 30 minutes).

The main issue is that it fills up my SSD, so every time I have to go to the .git folder and delete everything in there so it doesn't corrupt my world.
