When you launch Minecraft I have got it narrowed down to it being a problem with Alib, when launching Minecraft it crashes the game mid load up and says:
The game crashed whilst initializing game
Error: java.lang.RuntimeException: java.lang.reflect.InvocationTargetException
Exit Code: -1
When not having Alib in my mods folder the game loads up totally fine for me this is for Minecraft 1.16.3 and Forge version 1.16.3-34.1.17
