Sims 4 crashing during game play

Ok thank you so much for your help!

@Audr3y16  There are a couple of things you can try, if you're still interested in experimenting.  I don't know whether they'll help without uninstalling the Windows security update, but at the very least, it would be good to know that nothing worked.

Please set exceptions, in all antivirus/firewall programs you have installed, for both Origin.exe and TS4_64.exe.  Please also set an exception in Controlled Folder Access (a feature of Windows Defender) for both.  It should only be necessary to add TS4_64.exe, but might as well be thorough.  Here's how to change Controlled Folder Access settings:

Please also remove your entire Sims 4 game folder from Documents\Electronic Arts while testing.  A clean folder will spawn each time you launch the game, as long as it gets far enough.  Be sure to delete this clean folder after each test.

In addition, temporarily disable OneDrive (no need to uninstall it) while testing.  Here's how:

If these steps don't work, please try all of it again, this time adding another clean boot.  Here are the same instructions as before:

I understand how frustrating this must be, but the more information we have, the sooner we might find a solution.  All we know right now is that some people with the security update can still play, and that uninstalling it doesn't help everyone.  More information is always useful.

I tried everything you said and it didn't change anything. So, I uninstall the last security update from windows. I tried to play with my saves and the game crashed. After, I played with a clean folder. And i played for a long time. I didin't crash. So I tried putting my save in the new folder and the game crashed again. 

Is my save files the problem?

@Audr3y16  That's interesting; thanks for the update.  You tried using a clean game folder a couple of times before, where your saves wouldn't have been loading, and that never helped.  But apparently the combination of uninstalling the security update and removing your existing saves fixed the problem?  What happens if you leave your old saves out of the game folder, but you try to load a new save that you've just created today?  I'm just wondering whether the problem is something about your old saves, or whether it's the fact that there are any saves at all in the game folder.

@Audr3y16 @BlackHatSims and @Chonkerino  Please try disabling RivaTuner Statistics Server or MSI Afterburner.  A couple of players have reported that RTSS is the problem, and that it ran even during a clean boot.

@puzzlezaddict Thanks for the tip! I suspected that Riva Tuner Statistics Server had been causing my DirectX crashes but disabling it had no material effect on the game, the crashes persisted with the same frequency and severity--CTD often, BSOD only slightly less often.

I'll share that what ultimately fixed the issue for me was to run a BIOS update on my motherboard. It was running a years-old and very out of date BIOS--that predate all of the most recent predictive execution security fixes and the like.

After updating BIOS and ensuring that all of my device drivers were up-to-date and Windows was updated to 1903, all of the random/intermittent CTD and BSOD completely stopped.
