My custom Blockbench entity model crashes the game.

Hello. As you can tell by the title. I have a bit of a problem on my hands. I am currently in the process of developing a mod with MCreator and I have just spent several days designing and animating a hostile mob through the use of blockbench. However, when I attempt to spawn the entity in game with a spawn egg, the game promptly crashes. I tried using the vanilla spider model, and it worked. However, the texture was distorted since it was made for the custom model. It seems like my custom animated blockbench entity model is unable to be rendered in game. It is an animated .java file and made using the GeckoLib plugin on blockbench. (and yes, I have already installed it on MCreator) Here is the crash report in the MCreator console:

I tried things such as putting in a non animated model, but it still didn't work. If you could find the solution to this, that would be great.
