CasualSimmer4096 Did you specifically use Display Driver Uninstaller to remove your graphics driver before installing the new one? If not, please do so now. It's important to eliminate the driver as a source of error, to the extent that that's possible, and DDU is the closest we can get to doing so.
If DDU doesn't or didn't help, please create a new admin Windows account and try playing there. Make it local, as in, don't link it to your Microsoft account. (You'll see the option to say you don't have this person's email address or other info.) You'll be able to sign into your existing EA account and launch Sims 4, but your saves and other user data won't be available. That's fine for now and can be addressed later if necessary.
Try first in normal boot mode, and if that still doesn't help, try a clean boot in the new account.
Please let us know which issues you see, if any, in a clean boot in the new Windows account.
Also, can you move this to the Technical Issues - PC category?
