@Gemmawho Please start by running a couple of basic checks on your Windows system files:
- Hit Windows key-X
- Choose either “PowerShell (Administrator)” or “Command prompt (Administrator),” whichever option is offered
- Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes into the window, and enter
- The system will start validating soon. If it throws an error, please list it here
- After it reaches 100%, hit Windows key-X again
- Again, choose “PowerShell (Administrator)” or “Command prompt (Administrator)”
- Inside the window, copy and paste “sfc /scannow” without quotes into the window, and enter
- Post the message you receive here
Restart your computer and check for Windows updates again, and if any install, restart your computer afterwards.
Next, please try playing a new save 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. Don't add anything to it yet; just start another new save in one of the base game worlds and see whether it freezes. You don't have to spend much time on it; when I'm testing like this, I just create a single sim and hit Randomize a few times.
If you get another crash, please try playing in a clean boot:

When you reboot, go through the Task Manager's background processes list shutting down anything that doesn't absolutely need to be running. Some programs don't get disabled in a clean boot, and in your particular case, please be sure to kill any Asus support software you find. Anything critical should restart itself, but if not, another reboot will restore it.
Any time you get a freeze, please check the Reliability Monitor for any related errors. Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a list of errors and updates with a column for each day. (Today is all the way on the right.)
For any error that happened at the exact time of a game crash (within a couple minutes), please click "View technical details," or right-click on the entry, copy the information, and paste it here. You can ignore any "Windows was not shut down properly" errors, but I'm interested in anything else. The RM may not update right away, so check back in an hour or so, and check the timestamp within the technical details—the one on the chart isn't always accurate.
