(SOLVED) Minecraft closes with an error

In version MCreator 2023.4, I tried to duplicate one of my mod elements (essence) and change its model. After that, I started the game, spawn the mob and minecraft just crashed with an error.
Since I used a Geckolib entity, I decided to duplicate a non-Geckolib entity, did the same thing and still the error crashes.
It is worth noting that if I create an entity in a new way without duplicating it, the game will not close
