Remote projects are all empty

I’m trying to open my old projects after getting a new PC and they all appear to be empty.
I’m trying to open them from remote, in the Unity Hub, and I get this message on each of them

When they open, the Assets folder is completely empty.
Few months ago they were all opening fine, so I’m really worried I may have lost everything I saved on the cloud for the past 7 years.

I tried deleting the Library folder to force unity to reimport everything, but still no luck.

Any help? They were supposed to be safe on the cloud…
