@lizzie221188 Try playing in a new admin Windows account. Make it a local account, as in, don't sign into Microsoft, and don't sync with any other services you normally use. You'll be able to sign into your existing Origin account and shouldn't need to redownload anything, but your saves and other content won't be available.
Let me know how it goes, and if you get another crash, I think it's worth doing some hardware monitoring, just to see whether anything's amiss. Download hwinfo from here:
https://www.hwinfo.com/download/
You don't need to install anything; just download the portable version, unzip it in Downloads, and launch it from there or wherever you like. (If you do want to use the full installer, be sure to click the button for hwinfo itself, not for lansweeper.) Restart your computer, open hwinfo, and click the button that's a sheet of paper with a + sign to start logging. Wait five minutes, then launch Sims 4 and play until it crashes, then click the same button to stop logging.
Upload the log file to a third-party filehosting site and link it here. Please leave it in .csv format, or if you upload it to OneDrive, zip it first.
