I tried to find a topic related to this but the Known issues-thread isn't working (I made a separate thread wondering about this!). My game has been laggy, but manageable lately, however, every time I close the game it says The Sims 4 stopped working and needs to be closed. Technically this isn't an issue, since it occurs when I am closing the game and as long as I separately save before closing I don't lose any progress. It still is weird and I thought I should ask about it. I don't use any mods or cc or anything extra in my game. I have tried to repair the game a few times but it doesn't fix the crashing.

Could you post a DxDiag?
Please follow this how to on how to gather your DxDiag.
You can post the DxDiag by attaching it to your next reply.
Don't paste it directly into your answer, because that won't fit.
Do you have any mods or CC (custom content)? Try taking that out.

Make sure your game runs on your GeForce card:

Also update that same card:
geforce.com/geforce-experience
Also try cleaning out your screenshots folder.
