@AgnieszkaMaria81 Even if Snowy Escape is hopelessly broken, which it doesn't seem to be overall, it still shouldn't be shutting down your laptop. If you're willing to try, I'd like to see the results of some hardware monitoring. Download hwinfo from here:
https://www.hwinfo.com/download/
You don't need to install anything if you don't want to; just choose the Portable version, unzip it, and launch it from Downloads or wherever you want. (If you would like to install, be sure to click the green button, not the orange one.) Restart your computer, and don't open any other apps. Launch hwinfo, choose "sensors only," and click the icon that's a sheet of paper with a + sign to start logging. Save the file to your desktop for easy access later.
Wait five minutes, then launch Sims 4 and play until your laptop shuts down. The log should still be intact up to that point; you can upload it to a third-party free filehosting site and link it here. Please leave it in .csv format, or if you use OneDrive to share, please compress it in .zip format instead.
