Blockbench Model Missing a Head?

Before I updated, MCreator was just crashing every time I tried to load a custom model from Blockbench. Now it still crashes, but instead of stating the version mismatch, it says this:

Caused by: java.util.NoSuchElementException: Can't find part head
at net.minecraft.client.model.geom.ModelPart.getChild(ModelPart.java:91) ~[forge-1.20.1-47.2.0_mapped_official_1.20.1-recomp.jar:?] {re:classloading,pl:runtimedistcleaner:A}

I have a part named "head" in the project file on Blockbench. How can I remedy this?
