Puella_mirabile Some of the crashes in your dxdiag are too generic to be of any use, and some look like what happens with conflicting software. So let's start there, with a clean boot. This is not a clean install of Windows, just a way to disable services that don't need to be running alongside the game.

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.
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.
Your computer's graphics driver is also out of date, to the point where it may not be fully compatible with the game. The crashes in your dxdiag don't look like what we usually see with a corrupt driver, but it's certainly possible that this is the issue. So if the clean boot doesn't work, or if you'd rather update the driver first, try this one from Nvidia:

It's the second-newest, just in case there's an issue with the very newest one. Run the installer as an admin: right-click the download and select "Run as administrator." Restart afterwards and before trying to play.
