Crashes when using texture pack or add-ons

Well there is a serious bug well when I put texture packs and complements in the world that I'm going to create 

My game crashes a lot my device gets hot and slow because at the same time that it has a texture pack and add-ons in the world the game automatically crashes 

I saw that this beta has functions for textures and add-ons but even if I activated these functions or if they have been disabled, the game still crashes
