I am Getting an Error Message while loading Minecraft

[Olenderman]

I just wanted to play with my friends on a modded server but Minecraft keeps crashing and I have NO IDEA what is going so the Error Message says:
The game crashed whilst rendering overlay
Error: java.lang.NoSuchFieldError: children
Exit-Code: -1
 

and the Crash Report looks like this:
