My game keeps crashing

KeeTheQueeen  Thanks for the dxdiag, which lists a few different kinds of Sims 4 crashes, which can have the same underlying cause or not.  The two most recent crashes point to the Nvidia graphics driver, so please do a clean uninstall of the driver, as described here:

Rather than reinstalling the newest driver, try one from December or January.  You can find older drivers here, but make sure to select Game Ready Driver under Download Type so the list goes back far enough.

It's easy to update to a newer driver with an older one installed, but the reverse requires another round of DDU, which is why it's best to start with an older driver and work forwards from there.

Additionally, if you've overclocked your GPU, please revert to stock speeds for now.

The XBox Gaming Overlay is also crashing, so if you're not using Game Mode or Game Bar, please disable both, under Windows Settings > Gaming.

Your dxdiag lists one python37_x64 crash as well, and these (and occasionally some other crashes in your dxdiag) have been linked with high-end Intel processors that the motherboard may overclock by default.  So if the above doesn't help, look for a BIOS update for your board, which may or may not address the issue.  If it doesn't, or you already have the newest update installed, try disabling CPU Turbo Boost in the BIOS Advanced settings.
