To add, the issue only seems to be occurring with my MC1.20.1 Fabric instance. My MC1.20.6 and MC1.21 Fabric setups seem to be working with this mod.

The crash was caused due to an incompatibility with Java 17; Java 21 worked fine.
Thanks for letting me know!

This looks wrong:

def targetJavaVersion
if ("${project.version}".contains("1.20"))
    targetJavaVersion = 17
else
    targetJavaVersion = 21

Mojang (unfortunately) did the Java transition on a minor version, MC1.20.5, not on 1.21.
MC1.20.4 and earlier should target 17, MC1.20.5 and up should target 21.

Edit: I updated my Fabric 1.20.6 instance w/ the latest version of FBG and it does seem to be working anyway. MC1.20.1 also works now.
