[1.17.x Fabric] Cannot Remap AW From Namespace 'named'

See original GitHub issue

Version Info

Minecraft: Java Edition 1.17 GeckoLib: 3.0.13 Loader: Fabric

Issue

After adding Geckolib to the Gradle buildscript, Gradle complains that it cannot remap an accesswidener from namespace named. It expected intermediary.

Confirmed caused by adding Geckolib.
Does not occur if Geckolib is removed from the buildscript.
