Every time I try to load or generate a world with Chroma Hills, it crashes.

I bought the Chroma Hills Medieval Village Mash-Up Resource Pack. And every time I generate a world without fail, within a minute of loading the app crashes. It occurs every time I try to load the generated world as well. Please fix, I paid 6 dollars for it and would like to be able to use it lol. I am running Minecraft Pocket Edition v1.16.200 on an iPhone 12 Max iOS 14.1.
