Sims 4 crashes

@reebeckaaz  Well, that's frustrating.  I'm pretty sure CPU use isn't the issue here since it's nowhere near 100% even when Origin is in online mode.  The next step would be to 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, for example RGB software or MSI Afterburner.  To be as thorough as possible, please test in a clean Sims 4 user folder (move the existing folder out of Documents\Electronic Arts and onto your desktop to let the game spawn a new one), and play both with Origin in offline mode and while your computer is offline.

You can just let the game run if you want; no need to put effort into a save that you might not use again.  If everything is fine, you can start adding back other functions, for example putting your computer back online. and then trying an existing save.  (In that case, copy the save to the new Sims 4 folder.)  Please do one thing at a time so that if you get another crash, it's more likely that we know the cause.

Additionally, please post some basic info from your next crash; you can find it in the Reliability Monitor.  Hit 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.  Right-click on an entry and select "View technical details," then copy the info and paste it into a reply.

You can ignore the earlier crashes; I'm interested in the ones that happen after you do all of the above.  Look for errors both that mention Origin or Sims 4 and that have a timestamp that matches the crash.  If you see more than one, that's fine, more info is better.
