BigTreeFeature Problem with recommended version of forge

[Meluna]

So... Whenever I open minecraft  with forge installed I can type in the forge commands but they do nothing and when i place or remove a block the game crashes. I tried this on 3 versions of forge, the latest 1.15.2 - 31.1.44, the recommended 1.15.2 - 31.1.0, and the one before the recommended version and they all caused me the same problem.

This is the error I get, someone already posted the same error but somehow solved it.

Thx for the help.
