When I try loading Thorns, the game crashes. I tried putting the original chart files from the original FNF but it still crashes.

EDIT: I played through all the weeks and Winter Horrorland also crashes the game.

I redownloaded the game and it works, so trying to modify game files makes Winter Horrorland and Thorns crash the game for some reason? It doesn't seem to happen in any other song.

Never mind what I said, even without changing any files, it still crashes when I try playing Thorns.
