Recently made a mod in Intellij for Forge 1.20.1 with everything seemingly working perfectly fine with 0 errors in Intellij although when I try to run it in-game the game crashes on startup and gives the error and now Im just confused as to what is causing this error. The game crashed: initializing game Error: java.lang.RuntimeException: null Here is the full crash log: (excluding system details) ---- Minecraft Crash Report ---- // I let you down. Sorry :( Time: 2025-04-18 21:33:42 Description: Initializing game java.lang.RuntimeException: null at net.minecraftforge.registries.GameData.postRegisterEvents(GameData.java:315)
