@keinluigi I don't understand either, but three people in a short time frame suggests something strange is going on, and that was my first thought. It would still be helpful to confirm that the files in your Sims 4 user folder aren't related to the issue, i.e. by removing them temporarily. If nothing else, it will help eliminate some possibilities.
I tried to get my game to start up and this is all happening to me now. I've done all the suggested fixes and still nothing. I get the "Game is already started" or whatever that message is. When I hover over the EA APP icon it shows a white screen with a little blue square thingy in the middle. I've never had problems with this game before. This is ridiculous. Is this tied to that whole updating EA APP thing 'cos mine is up-to-date, I checked. How would I even set the date back to get it to work and will it just stop working again when I get to this date? Look, this game is my happy place, if I can't access it, I'm not going to be a happy person! WHY does this app not work?!!!
UPDATE!!! I fixed this problem on my computer. It was the OneDrive being synced. I thought I'd unsynced it earlier but apparently I had not 'cos I just did it for real now and my game is fine. Thank god!
@keinluigi I don't know either, but possibilities include a change in the EA App and an update to your antivirus, whether it's Windows Defender or a third-party program. The important thing is it's fixed now.
