Game Crashing Unexpectedly

Hello!

So my game has been working fine with no issues until a few days ago. In the middle of gameplay, without any warning, my game would close instantly. I have no issues with the loading screens or extreme lag--it would just shut down in the middle of playing. And it wouldn't be like a few hours in, it would be like 20 or fewer minutes in real life and a few hours in-game. After it would crash, I would get "The Sims 4 quit unexpectedly' report. I don't encounter any error messages, no freezing before crash, anything that would indicate something else is at hand. 

 I have repaired my game, made sure all my mods and computer were updated, cleared caches, and I've run better exceptions for any mods that could be causing problems, but I wasn't able to find any.
