It looks to me like you’ve deleted your .git directory, I presume because you were nearly out of space. That’s why your Rewind is empty and why simply deleting that directory isn’t the best solution for that problem. Glitch full disk error is a better approach to dealing with this issue that retains your ability to Rewind while also helping with your .git directory growing too large.
Here is a list of backups we have for your project, along with their timestamp in UTC and their rough size; please choose one you’d like us to restore and let us know which one.
