Mcreator crashes when adding a mob

I need idol animations for every MOB I add in geckolib, are they included? Also, the name of the animation you give when you create the animation and the name you give when you set up the animation in mcreator must be exactly the same.

It is possible that this is a problem with the model file itself.
Import the model you created into your 'notepad' and check the code.

<T extends "Your model name">
If the 'model name' is specified in this section, you must modify it to 'Entity'.

<T extends Entity>
