Ran into the same problem. This dependency is required in the newest version

DUDE YOU ARE GOD, ty

Any time! In the future, this line here was the giveaway:
Caused by: java.lang.ClassNotFoundException: eu.midnightdust.lib.config.MidnightConfig

Just make sure to mark the issue as closed.

Ill close the issue when ive added midnightlib to the fabric.mod.json dependencies
