Sims 4 keeps crashing under Windows 11

@lunafantasy  This error is an access violation, which is quite generic: it can be caused by anything from mods and custom content to a game bug to software conflicts to a hardware problem.  So if you use any mods or cc, please test without that content, even if it's always been fine.

If you get a crash even with all mods and cc removed, please try playing in a clean boot:

The one service to leave enabled is the EABackgroundService, which the EA App needs in order to run.  Disable the rest as described.

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.
