How to Get my User game files back The Sims 4

@OddChild707  Please try doing a clean uninstall and reinstall of Origin:

• Quit Origin, then right-click on the Task Bar and open the Task Manager.  Scroll through looking for Origin entries.  If you find any, click on them and End Task.
• Clear Origin's cache.
• Download Revo Uninstaller (the free version is fine) from here.
• Launch Revo, select Origin from the list, and click Uninstall.
• When it finishes uninstalling, select "Moderate" under "scanning modes," and click Scan.
• If Revo finds any remaining registry entries, select all, delete, and click Next.
• Revo will display "Remaining Data and Folders.  Select all of them except for the "Origin Games" folder, if it appears.  (This is where Sims 4 and other Origin games are installed by default.)  Delete the rest.
• Close Revo, and restart your computer.

Next, download the full Origin installer and run it.  Here's the direct download link:

Be sure to run both the installer and Origin itself as an admin: right-click on each and select "Run as Administrator."

If this doesn't help, please look for relevant entries in the Reliability Monitor.  Hit Windows key-R and enter "perfmon /rel" without quotes.  You'll see a list of errors and updates, with a column for each day.  (Today is all the way on the right.)

For any errors that mention Origin or Sims 4 reinstall Origin, click "View technical details," then copy the information and paste it into a reply here.  Sometimes the Reliability Monitor doesn't update right away, so if you don't see any related errors, be sure to check back an hour or two.  The timestamp on the initial chart can also be off by up to an hour, so that's not an entirely reliable metric, but the one within the technical details should be accurate.
