Geckolib entity won't work please help

Hello, I've been building this mod recently, adding features and realising ideas, and now it was time to implement the first entities. I am using Geckolib for animations, and I have used Geckolib before in older Minecraft/MCreator versions. I get the newest Geckolib version for 2024.3 and create Geckolib animated entity, put in texture and Geckolibmodel from Blockbench, but this "animated entity" spews 20 plus errors. Idk whats wrong, I am no code expert, something Geckolib is messing up. Please help, I will provide as much information as possible.
