@mj561256 Those temperatures are all fine. The graphics card will throttle a little when above 70º, but it's not really a problem until it hits 80, or the hot spot gets into the 90s. The processor can run comfortably in the low 90s as well, and other components should be perfectly fine up to at least 70; the exact temperature at which heat becomes a problem will vary depending on the component and the sensor. Point is, it sounds like this isn't the issue.
Your dxdiag shows that Sims 4 is crashing due to an access violation, which is, unfortunately, an extremely generic error. Causes range from mods and custom content to in-game bugs to interference from third-party software. So troubleshooting this error can be a bit of a guessing game.
On that note, please try playing in a clean user folder. Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content. (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.) Don't add anything to the new folder yet; just start a new save in one of the base game worlds and see whether it crashes.
If you do get another crash, please try playing in a clean boot:

The one service you need to leave enabled is the EABackgroundService, which the EA App needs in order to run. Disable everything else as described. When you reboot, go through the Task Manager's background processes list shutting down everything that doesn't absolutely need to be running, for example any Asus support software is extraneous here. In particular, make sure to disable Asus Aura, a component of which has also been crashing. It might be bundled into ArmouryCrate rather than being a standalone app, but either way, it shouldn't be running during this test.
If you accidentally kill the wrong process and it doesn't restart on its own, you can simply reboot your computer, so don't worry about shutting down something essential.
If you get another crash, please repeat the test, except this time, play while your computer is offline. You can put Steam and the EA App in offline mode after signing in, then disconnect your computer from the internet before pressing Play. Some people report that their Steam-owned DLC doesn't load while offline, but that's fine for the purposes of this test.
Please continue to run a new save in a clean user folder, at least until the game stops crashing. Then you can start adding things back, both your content and the programs disabled in the clean boot, and see what makes Sims 4 crash again.
