The issues started when my computer told me that my one drive was running out of space on my computer, so I started deleting geodatabases which I thought were old and not my main project geodatabase. I ended up deleting the geodatabase that had my models. Luckily, I had all my files on my one drive, so I restored my one drive. I thought that would solve the problem. I can see my geodatabases on my online OneDrive, but I can't access them after I synced them on my computer. Maybe the syncing is still working, but that's kind of insane because it's been syncing for around 15 hours. Everything will sync, aside from my large geodatabase (10K items) which has all the files I created for my thesis.
I tried downloading the databases directly from one drive, but the files just have tons of errors and will not open.
I have talked with my professor at my university, microsoft support, and esri won't help me directly because I have a student account.
