Blockbench Model Not Compiling in 1.20.1

I've seen several posts similar to mine, but I haven't found a solution yet. I imported a model from Blockbench into MCreator for one of my mobs and now my game keeps crashing before I get to the main menu. I verified that this model was the problem, because it loads up perfectly when a different model is selected. Upon further inspection, I noticed that there seems to be a version mismatch. What should I do to remedy this?
