A DESCRIPTION OF THE PROBLEM :
I am using MCreator to make a Minecraft mod and every time I try to run the client I get this error when it reaches the :runClient step. Please help me, I have already checked other forums and none of the fixes I have tried so far work. (I don't know if that is the real subcomponent it was just required)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I don't know it just happens every time.


FREQUENCY : always
