Over 100GB of data disappeared. Help?

I just turned on my laptop and I was quite surprised to see that all of the folders and files on my desktop disappeared. Initially, I saw them in the file explorer, and my C drive had about 200GB of free space. As I was downloading updates on Windows 11, busy on the phone and whatnot, now more free space appears on the C:. I don't know what happened during that time. A virus scan doesn't turn up anything. What do I do now? Is there any way to do a restore and see if those files turn up? This is on an SSD and IIRC, there is a way to recover the files? Unfortunately, I didn't back up those files to an HDD so it's important to find a way to somehow recover them.

I don't know if this is related to Onedrive. I noticed that after this latest Windows update, OneDrive seems to have been turned back on and synced my files to OneDrive. I know files were backed up because there is a desktop folder with subfolders that range from 1-19. Unfortunately, some folders are empty. It makes me wonder if OneDrive was automatically deciding what to backup? Like if an existing folder with the same name exists on OneDrive, would it only back up the folder from my laptop and then delete the files if it seems to exist on OneDrive? I tried to do a restore via OneDrive to a previous date, but all my lost files don't exist using a previous recovery date.
