Game keeps freezing

@Louisa12334  You've installed the correct graphics driver, but the same errors appear in this dxdiag as in your last one.  So please do a clean uninstall and reinstall of the driver, as described here:

Please also check the GPU's temperature while you play.  You can do this somewhat crudely through the Task Manager's Performance tab.  It's not the most accurate reporter, but this should at least give you an idea of whether this is a problem.  Anything below 70º C is great; anything below 80º is good enough to avoid heat-related issues.

If DDU doesn't help, and temperatures are fine, can you borrow a different graphics card from a friend or family member to test with?  Could someone you know test your graphics card in their system?  It's possible the GPU itself is dying, and the only way to know is to isolate it from the rest of the system, either by testing it in a currently-working computer or testing a different card in your computer.

If this isn't currently possible, you could remove the GPU from your computer and plug the monitor directly into your motherboard.  Your processor has integrated graphics, and while performance would be relatively poor, Sims 4 should still run on the iGPU.  So it would also be a useful test, although not as much since this removes several potential points of failure at once.
