Sims 4 game keeps turning off

@jula141207  I actually wanted the Processes tab, not Performance, so I could see how much memory Sims 4 is using in addition to your system overall.  But these screenshots at least tell me that your computer wasn't close to running out of memory at the time.  If you play one of your affected saves forward, do you still get the out of memory error?  Please let it run for a while to find out.

Every ten minutes or so, take a screenshot of the Task Manager's Performance tab, and post the last screenshot you take before the error happens.  You don't need to save all the other screenshots; the last one taken will be saved in the clipboard, accessible by clicking the notification icon in the lower-right corner of the screen, and only replaced when you take a new one.  You can leave the game in windowed mode for convenience, and you can also simply let the game clock run without actively playing if it's more convenient, since this is just for testing.

In addition to the screenshot, please also let me know how long it takes for the error to show up.  If you never see it, think about what circumstances triggered it before, for example being on a certain lot or waiting until a certain time of the sim-day or -week, and try to replicate that.
