Mecojoni

Hi everyone, as the title suggests I modified my pokemon sword rescue in order to continue the adventure in pokemon shield, and everything worked ... until I got to the ghost-type gym and ... I found that fight type ... I say "strange, oh well" and I go on and everything works ... but when I got to what was supposed to be the ice gym and I found that rock I crashed the game, as soon as I entered the gym ... I don't really know what to do, can you help me?
