Star Wars Mash-Up Not Loading

When I try to open the Star Wars Mash-Up world it only loads the sky for a few seconds and then makes the whole app crash. The same happens when I try to open my other worlds with the Star Wars texture pack. I’ve made sure my Minecraft app and my iPad OS are both fully up to date, but I’m still unable to access the Star Wars Mash-Up world and worlds with the Star Wars texture pack.
