Can't Launch mod with Geckolib as dependency

[ToasterDan]

I am trying to use Geckolib while making a mod for 1.19.4.

First I made a mod myself in IntelliJ and followed all of the steps detailed in Geckolib's own guide on installing it as a dependency in your mod. I tried running the client, but the game instantly crashed. I then tried using Mcreator with the Geckolib plugin, and made the workspace use Geckolib as a dependency. I followed the official guide of the plugin on how to install it. When I try to run the client, the game instantly crashes with the same errors.

Why does this happen, even if I follow tutorials and guides precisely?

How do I fix it?
