Forge crashing upon pressing play in launcher. Version 1.10.2 - 12.18.1.2026

[BudgieBud]

This is my first day with minecraft forge. I have installed the 1.10.2 version. It all works but once i click Play in the launcher, It begins but as soon as "MOJANG" comes up, within a split second the game crashes.   

 

I am in the versions: 1.10 - 12.18.0.2000 to 1.10.2 - 12.18.1.2026

 

 

This is the error message in it's entirety:

---- Minecraft Crash Report ----
