Game freezing and crashing after update

@landstriderx  Please test with no mods or custom content present, in fact test in a clean user folder.  Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content.  You can download this existing household from the Gallery and see if the save starts getting larger.  If it does, then please test with new sims you create fresh in CAS.  You don't have to spend much time on them; the point is to test completely fresh content.

If your Gallery sims are fine in the clean folder, you can start moving over your mods and custom content and testing again.  The 50/50 method is the most efficient approach.

Here though, instead of just seeing whether the game loads or crashes, please check the save file size.  A new save should be around 5 MB in size and grow only very slowly; even after a very long initial play session, I'd expect it to be no more than 8 MB.  Any time the save grows much faster, you'll know that one of the files you added back is a problem, and you can split that last batch and retest until you find the culprit.

I would love to know which mod or cc item is causing this, or items plural if you find more than one.  At least several other users have reported the same issue, with potentially dozens more affected (not enough info to say), and as far as I can tell, all of them used mods and/or cc at one point.  So it would be great to know what exactly is triggering this issue.
