I've been having this issue for 24 hours now. It worked fine yesterday until about 2am then when I tried to play at 7pm it just kept relaunching the EA app and not starting the game at all. It's still doing it today. I'm at a loss as to why it's doing it or how to fix it. I moved the saved folders as suggested elsewhere and nothing changed. DxDiag attached.
LadyVampy13 To be clear, did you try moving your entire Sims 4 folder out of Documents > Electronic Arts? If not, please do so now.
Please also disable Game Mode and Game Bar, both under Windows Settings > Gaming.
If that doesn't or didn't help, please look for new errors in the Reliability Monitor. Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day. Today is on the right.
Look for an error that happened at exactly the time of your most recent attempt to launch Sims 4. If you find one, double-click it to see more details, then copy that info and paste it into a reply here. If you don't see a new error, check back in an hour or so—the Reliability Monitor doesn't always update right away.
