kirasparkle I've just seen your post and update, and that's kind of fascinating. Would you be willing to provide a bit more info so I can recognize this issue if and when it shows up for other people? I'd specifically like the Reliability Monitor report from one of these crashes. This doesn't have any personal info, just a brief log of the crash that might include something recognizable.
Click Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day. Today is on the right. Look for an error that happened at exactly the time of a relevant Sims 4 crash. If you find one, double-click it to see more details, then copy that info and paste it into a reply here.
