Bug description

Elytratrims prevents loading of new and existing worlds in my modpack, worked fine on 3.5.0.

Discovered initially when attempting to boot my server and it errors out.
I've tested in a clean Forge 1.20.1 installation, with only Kotlin and ElytraTrims installed, and that functioned fine when I created a world.

Creating a new world immediately crashes, with it citing ModernFix as an additional potential cause - However I added this to my test installation with just ElytraTrims and didn't experience the same issues.

Steps to reproduce

No response
