Sims 4 Lagging, taking forever to load, not responding

I’ve had a similar issue. Basically i can open the sims 4 game itself completely fine, no problems, but when i’m loading into a household, it takes forever(or a really long time) to load and actually get into the game play. And when i load up my game and finally get into the household it’s laggy at first but then fine, but everything keeps lagging and freezing. my biggest issue is when i’ll tell my sims to do something, or if they’re already doing something or even if they’re doing nothing, the time will freeze and whatever speed it was in they’ll do a little motion in that speed. this problem used to not last that long and stop on its own and i could play, but it’s gotten worse so if it stops on its own it take very long and now it doesn’t even stop. so i’ll try to leave the game and save it and when i’m saving it my game will crash. also saving takes forever and when i’m trying to do things will this lagspike is happening, everything his really slow.
