My game crashes and I can't fix it. it says exit code: 0

Everytime I try and launch minecraft it goes as planned, preparing, launching, etc, 

then when I reach the mojang loading screen it closes and puts me right back to the

minecraft launcher. It says, "ERROR Game crashed An unexpected issue occurred

and the game has crashed. We're sorry for the inconvenience." Then below that

message it says" Exit Code: 0" I don't know what to do and I can't fix it. I am playing

Vinilla Minecraft with no mods. I don't know what I could have done to do this.

Im sorry Minecraft gods!
