I have been troubshooting this issue for weeks now and now one at Adobe has been able to actually help me. I have had these files on my school enterprise account for 10 months now and I just recently started getting this error. This project file is super important so any help would be super appreciated.
I have tried signing out and signing back in to everything multiple times and that has not worked. I looked at that thread and I am ceratin I am signed into the right account. If you watch my video above, you can see that my files appear for a seccond before that error screen apperars
