Geckolib animations stop working after the first entity

Hello people,

I have had a problem with  animated entities not performing their animations. When I created the first model, everything was fine, with the first model's animations running as normal. But after this all the animated entities I create don't play any animations and geckolib stopped being fully loaded. I have tried recreating the workspace but the same happened. I haven't found anyone that has experienced this problem, so I created this post to ask for help and potential fixes. I might also post a bug report for this.

Cheers!
