My game crashes when I try and use this texture pack

So one day I got this fantasy texture pack in the Minecraft store I later use it in a couple of my worlds but then all the sudden when I try to create a new world with the texture pack the loading screen turns into groups of black and pink squares about a 4 by 4 in each group then my game crashes and my ps4 gives the error code of (CE-34878-0) I don't know if maybe the texture pack got corrupted or maybe my ps4 cant handle it I paid money for this texture pack and I would either like a refund or it to be fixed the name of this texture pack is "Fantasy Texture Pack"
