@Bananarolls  Try playing in a clean boot:

If that doesn't help, I do wonder about the sound card, which doesn't have a newer driver available from Asus, unfortunately.  How difficult would it be to remove it temporarily?  The reason I ask is that given the AppHangB1 errors, normally the next step would be to do a clean uninstall and reinstall of the graphics driver, which is a bit of a process.  So take your pick.

For the GPU driver, start by downloading Display Driver Uninstaller from here:

I've seen a couple reports of the newest Nvidia drivers not getting along with Sims 4, not enough to signal a significant issue, but worth accounting for.  So instead of installing the very newest driver, try this one from December:

Next, take your computer completely offline—disable wifi and/or pull the ethernet cord—and double-click the DDU.exe.  Take note of where the file will land, and click Extract.  If it's easier, you can copy the path and then paste it into the address bar in a File Explorer window.  Open the folder and then launch Display Driver Uninstaller.exe, and you'll get a message that you're not in Safe Mode.  Click OK, then go to Options and enable Safe Mode dialog.  Here's a screenshot of what your options should look like; make sure the box in red is checked:

Close options, and the DDU, and then open the DDU.exe again.  For launch options, choose "Safe Mode (Recommended)," and then click Reboot to Safe Mode (you'll need your password, so find it before rebooting).  Once you login, you'll see this:

In the blue box, choose GPU, then Nvidia if it's not already showing.  Then click Clean and Restart (red box).

Once your computer has rebooted, now back in normal mode, run the driver install .exe in custom mode.  Select "perform a clean installation" and install ONLY the GPU driver and the PHYSX software.

Reboot again, go back online, and let me know whether the game works.
