Please help me as soon as possible— the game just won’t run.

sgdsh666​  Your lastcrash didn't attach, but that's fine, no one outside of EA can do much with it anyway.  A dxdiag is always appreciated though.  In your case, however, it doesn't list any Sims 4 errors, or anything else that's a clear issue.

I would suggest updating the graphics driver though, since yours is 16 months old.  Rather than installing the newest driver right away, try version 577.00 (the Game Ready Driver), which was reasonably stable; some of the newer ones have not been.  You can get older drivers here:

If you get another crash, please look for new errors in the Reliability Monitor.  Click 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 Sims 4 crash.  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.

If you see multiple errors from when you were playing after updating the graphics driver, I'd like to see them all; just let me know which one(s) happened at the time of the crash and which were earlier.

Thank you for your help. Here is the information I found following your guidance.

sgdsh666​  This is an access violation pointing back to the game itself, meaning it's unfortunately not providing any more information.  So you may need to do some experimenting to get the game working.

Before anything else though, if you're in a region that has a local version of Steam, are you using that or the international version?  Sometimes the international version stops working in places that aren't supposed to have access to it.  The local version typically works as normal.

If that's not the problem, please remove or rename the Sims 4 folder in Documents > Electronic Arts.  The game will create a new folder with no content when (if) it launches.  Don't add anything to that yet; just see whether you can get far enough to start a new save.

If that doesn't work, try again, but with your computer offline.  You can sign into the EA App and put it in offline mode; I think Steam has a "Go offline" option too.  Take both offline, then disable wifi and/or disconnect the ethernet cable before pressing Play.  If that helps, you can try with the launchers in offline mode but your computer online.

If it doesn't help, try playing in a clean boot, offline first then online if it helps.

One service to leave enabled is the EABackgroundService, which the EA App needs in order to run.  Disable the rest as described, unless Steam (or Epic) has a necessary background service as well.

When you reboot your computer, go through the Task Manager's background processes list shutting down any service that doesn't absolutely need to be running, for example anything from MSI Afterburner to RGB software might still be enabled.  If you accidentally kill a critical process and it doesn't restart on its own, just reboot your computer again.

Don't open anything other than Sims 4 and the EA App while testing, not even a browser window.

If this helps, you can selectively reenable services until you find the culprit, then either leave that disabled or (if it belongs to an app you want to keep using) let me know what it is so we can try to fix the underlying issue.

Thank you for your help! I can now run it smoothly after reinstalling the system. Hahaha!😄

sgdsh666​  Do you mean you reinstalled Windows?  I hope you didn't have to do all that, but maybe it was worth it to get back into your game sooner.
