Armor Model Crash

I can't believe I'm actually asking this already, but this program just keeps crashing. I was making a helmet model in Blockbench, and I knew I was going to have issues with the pivot points because, for some reason, whenever I move them around, the whole model gets messed up. But when I uploaded the model to Mcreator, it said build failed. https://pastebin.com/PEVfkXuS
