OneDrive files disappeared

Hello...

We are having a big problem with one of the computers of the company.

The computer is a Mac with 12.4 (Monterey).

OneDrive was working normally, but suddenly, in september it stopped working, I think because Microsoft made an update. After that, the sync wasn't made but the user continued to work on the files in the Mac and never realized that the sync wasn't being done.

Only last week the user noticed the sync problem and then she started to prepare the files to copy to the server using a web browser and also was continuing to work the files in the mac, locally.

But yesterday all the OneDrive files just disappeared, I can't find them no where, and since they weren't doing the sync, they aren't in the server.

Where are the files ?

Thank you,
