1.20.1

The Issue

I created a custom model for the Kobolds! mod in Blender 3.6. I was able to succesfully import the model and armature into the Datapack Editor, but after I try to get into the animation select menu by clicking into the magnifiyng glass icon, the games crashes giving me this issue's title. I'll place the crash log and my model here. I asked ChatGPT about it, and it most likely is an error with animations, but I couldn't tell, I'm new to all this.

Steps to Reproduce

At Blender:

• Select Model and Armature -> Export it with the json addon -> having all squares ticked or excluding animations export didn't make any difference

At Minecraft:

• Import the json file -> choosing my custom model and armature -> hovering over to Living Animations -> add category and clicking the magnifying glass to open the animations menu -> crash
