I was working on using a simple blueprint interface to use between a character blueprint and an animation blueprint. I wanted to modify the interface and add an output (it had no inputs or outputs before that). It worked the first time I did it, then suddenly everything froze, a couple of seconds later UE4 crashed and closed. The problem was when i was loading it again it doesnt open, it freezes at 93% and then crashes again.
I tried removing my maps from the DefaultEngine.ini file and it worked, but when i tried to open the either the character blueprint or the animation blueprint it didnt work, actually just doing a single click on them crashes UE4 again.
Does anyone know if i can restore these files somehow ?
