@LittleGraveRaven Please check for any new errors in the Reliability Monitor. Hit Windows key-R and enter "perfmon /rel" without quotes. You'll see a list of errors and updates, with a column for each day. (Today is all the way on the right.)
For any errors in the last two days that mention Origin or Sims 4, or any that happened at the same time as a crash, click "View technical details," then copy the information and paste it into a reply here. Sometimes the Reliability Monitor doesn't update right away, so if you don't see any related errors, be sure to check back an hour or two. The timestamp on the initial chart can also be off by up to an hour, so that's not an entirely reliable metric, but the one within the technical details should be accurate.
If you don't see any related errors, that's useful information too.
