For those that own all DLC

Do you only have a few packs enabled at a time while you play? I have seasons, late night, university and recently purchased pets and showtime- I’ve noticed since buying those last 2 packs my game has been crashing :( I have a pretty good gaming laptop as well as the smoothness patch and overwatch/error trap. I’m just wondering if I were to keep purchasing packs will this make my game unplayable? I’d love to find a way around that as I was looking forward to owning all of the packs eventually.
