MC 1.17.1 | MAC OS 11.6 | Forge 37.0 - java.lang.reflect.InvocationTargetException: null - SOLVED

Seion · October 26, 2021

So I was getting the "java.lang.reflect.InvocationTargetException: null" error when launching forge from the vanilla launcher with no mods installed. I removed Minecraft completely and reinstalled everything and reinstalled forge and same error.

I removed it from the Applications Folder.

I then deleted everything I can find minecraft related from

~/Library/Application Support/minecraft

~/Library/Caches
~/Library/Preferences

~/Library/Saved Application State
