Help Recovering Overwritten Save File for The Sims 4

@busiasrusia123  Unfortunately, you've already looked for the content in almost all the places it would exist.  It's possible you could get lucky with OneDrive, if it's ever synced your Sims 4 data.  Try onedrive.com, both My Files and the Recycle Bin; look for saves with the correct date, even if they're named in an odd format.  Other than that, the data is likely gone.
