Sims 4 Crashing to Desktop

@PodaTheHutt  Some of the Sims 4 errors in your dxdiag do look like they might be related to the graphics driver, although it's not always clear with these types of errors.  Try doing a clean uninstall of this driver and installing a slightly older one, from November, which you can get here:

Here's how to clean uninstall and reinstall the driver:

If that doesn't help, try playing in a clean boot:

When you reboot, go through the Task Manager's background processes list shutting down everything that doesn't absolutely need to be enabled, for example RGB software or utilities like MSI Afterburner.  If you kill the wrong process by mistake and it doesn't restart automatically, just reboot your computer.
