Folder disappeared from DOCUMENTS

I had a folder in iCloud Drive but I moved it to documents on the Mac to take up less space as it contained files I didn't use frequently.

The aforementioned folder is gone, in fact I can't even access the Mac Documents because I get this message:

"documents cannot be opened because the original element cannot be found"

I called Apple but they don't understand the problem.

The folder is NOT in the trash is completely gone.

Among other things, I tried to move other files in the mac documents to understand what could happen or if at least I was able to open them and this happens:

"you can place items in documents but you will no longer be able to view them. continue?

other users with sufficient permissions will be able to use these elements "

Anyone have a solution?

Thank you
