I am a CIT pack enjoyer and I started using fabric lately instead of forge to play minecraft. Originally I started a world with optifabric in 1.19.2, no issues there with loading the resource packs and CIT packs but I converted the world to 1.20.1 because I wanted to use the cherry logs in my builds. But now minecraft struggles to load in if I use more than 6 resource packs/CIT packs at once and even if I remove some of them it stays bugged and doesn't load instantly. Its just stuck loading and I don't know how to fix the problem. I tired the same amount of resource packs/CIT packs in forge and in the 1.19.2 optifabric and minecraft loaded up no problem. Can anybody help me with what I can do?

if you load in a completely new world do you still have issues?
