@cursdgamerchild Try uninstalling and reinstalling the EA App. Clear its cache first:

@cursdgamerchild Does this happen if you put the EA App in offline mode before launching Sims 3? I've never seen this particular error before, so I'm trying to narrow things down here.
If you use an antivirus, please also try disabling it while you play; your computer should be safe as long as you don't do anything else. And let me know whether OneDrive is running, even if you never use it. It would be strange for OneDrive's syncing activity to make the EA App think the game is still open, but the App is quite invasive and acts in somewhat illogical ways, so who really knows.
@cursdgamerchild Try disabling any overlays, notifications, and anything else you can reach within the EA App's settings. Or you can continue to play with the App in offline mode and hope this issue gets patched—the App is still very much a work in progress, with a number of features currently getting attention.
