candid_flower01 I apologize for the late reply. If you moved your saves folder out of the Sims 4 folder, that would be why the saves aren't showing up. You can try moving one or two saves back to see whether they load; make sure the files end in .save rather than .verx , which denotes a backup.
If your saves are back in the saves folder but not loading, please post a screenshot of the contents of the saves folder, as in, I'd like to see the file names and sizes. Include the address bar, above the list of files, in the screenshot.
