launcher crashes with forge

I have played Minecraft for around 8 years, I never really use mods but I know how to and have before. Im not sure if this is an issue with forge or with the launcher but suddenly when I tried to launch forge 1.15.2 31.1.18 it instantly said, sorry the game crashed.

 

sorry I don't have more information on it but help would be appreciated
