Im running Forge on a MacOS and I have tried forge with and without mods.
After each attempt this error code pops up in the launcher:
The game crashed whilst initializing game
Error: java.lang.ClassCastException: net.minecraftforge.fml.ModLoadingStage$$Lambda$3094/157971930 cannot be cast to net.minecraftforge.fml.ModLoadingStage$EventGenerator
Exit Code: 255
The stuff that appears before it crashes at the bottom left says
"
completed deep scan of forge...... client
completed deep scan of forge...... universal
"
Numbers are there i just couldnt be bothered to type them out.
thank you
