Sims 4 Random game freezing, even after repair and updates

@Stephen_Mulhern  Sorry for the late reply.  I can see where the game froze in this hwinfo log: the CPU and GPU activity drop considerably, all of a sudden and at the same time, just before the log ends.  There's no obvious reason for it though—everything looks fine right up until that point.  The only detail I noticed is that your system downloads something, there's no indication of what, a few seconds before the system downclocks.

Connection issues aren't my strong suit, so I can't really tell you why this would freeze your system, or even how plausible it is that this is in fact the cause.  But it's easy enough to test: play while your computer is offline.  You can sign into Origin and put it in offline mode, then disable wifi and/or pull the ethernet cable before launching the game.  The download happens over your Broadcom wireless adapter, not the ethernet; I don't know whether you even have ethernet hooked up.  But if you do, and playing while offline works but isn't a good long-term solution for you, you can try just disabling wifi and letting your computer use the ethernet connection.

If this doesn't help, let me know; I want to get a second opinion from someone who's better at these kinds of things than I am.
