Freezing/crashing

Hello, this is my first post here so I apologize if I do anything wrong.

My game has been crashing (particularly in build-mode but also outside of it) and/or freezing since I downloaded the nursery kit last year. I use some basic mods (primarily **bleep**), but even turning them off doesn't seem to help at this point. They've been inactive/turned off in game for months. I have uninstalled and reinstalled the game entirely, and this also didn't help. I use an NVIDIA driver and always have, and recently installed a different, earlier version in an attempt to fix my issue. It did not.  I have searched through the sims 4 discord as well as various forums, EA-run and otherwise, and none of the solutions offered have helped. I have tried everything I've been able to understand. 

At this point, I can play maybe 5 minutes if I'm lucky. It's been about a year now that this has been happening. I keep up with updates, and repair the game/packs regularly. I'm very frustrated because I've spent a lot of money on this game, and I've had it since it came out. I got the first pets pack on disc I've been playing for so long. I don't know what to do, and I'd really appreciate some help/suggestions on how to fix my game. 

Thank you.
