Lagging with packs

I got some packs for The Sims 4, a good amount of them, on my PS4, and my friend also has them on her PS5. The lag and crashing are terrible. Every 5 seconds or so, I lag out for 10-25 seconds. It's a little annoying because it takes me a lot longer to build or even play. I feel like if you have the packs, the game should support more than 6 packs at once. It makes it annoying to play. Is there any fix for this, or any way to fix it? I would like that. Thank you.
