Compiling ThirdPersonCharacter make UnrealFreeze

UE4 FREEZE when i compile ThirdPersonCharacter BP when this nodes

are present. I can when i delete it, but CRASH when i undo the delete. However i can play in the editor, ignoring blueprint unresolved error, what compile my Bp and make it “good to go”. I tested it and this works fine; simply i can’t compile manually, wihch is very annoying.
I tried to compy it in a actor bluprint to see if the same issue appear, and exept the obvious errors, i can compile without freeze.
