can anyone help me fix my data pack?

the data pack is for a server i'm making (1.21.11), and i'm aiming to make end cities, trial chambers, diamonds and ancient debris rarer while also making golden apples cheaper and ender eyes more expensive. for some reason my game crashes constantly when attempting to load it.
