Project Missing words & Backups Won't Open?!?!?

I opened a project this morning to find words missing and parts of it reverted to an earlier version. No problem I go to my backups folder, click on a backup to extract it and windows says the zip files are empty even though they are about 1.3MB.

When I try to recover the backups using zip recovery software it shows no files in the zip folder.

What’s going on? How is this possible and how do I fix this?
