@steviecraig I don't think it's time to start wondering about your graphics card yet. Still, if you never ran stress tests after installing it, now would be a good time. I believe the demo of 3DMark is still free on Steam if you're interested. No need to buy the full version; just run Time Spy and Firestrike and let me know if you see a crash or any other problems, or if 3DMark says your scores are significantly below what it would expect for your hardware. You can also link me the results pages without creating an account.
Again, I'm not saying your GPU is the problem here, and it's still less likely than other possibilities. It's just that this kind of test is always a good idea when building a new system or even installing a new core component. If you get the equivalent of a pass, that's not absolutely conclusive, but it means that a hardware problem is very unlikely.
Your new dxdiag shows one new Sims 4 crash and a bunch of Edge update errors. I noticed a few days ago that Edge had set itself to start with Windows after an update, even though I would never allow this, so please double-check your settings as well, specifically the Startup list in the Task Manager. If nothing else, you'll claw back some resources, especially if Edge can't update itself properly and is falling all over itself in the attempt.
For Sims 4 itself, please try playing in a clean boot:

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.
