malavu To be clear, you moved the Sims 4 folder out of Documents > Electronic Arts, and you did NOT add anything to the new folder the game created? Please open this folder anyway and look for any saves or Tray files in case OneDrive restored some of your content.
If that's not the issue, please provide a dxdiag. Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
