[Help] AIControllers Blackboard

Hello, Im trying to initialize the blackboard in my custom AIController class, I tryed to do this in the constructor with
CreateDefaultSubObject, And also with the constructor that usses the ObjectInitializer parameter. But the output log keeps printing out that the variable Blackboard is null.

Blackboard is located in the AIController class under a protected acces level, But how do I use it if I cant seem to initialize it in the first place.

My thought at the moment is that I cant use CreateDefaultSubObject in a childs class to initialize a parrents variable,But that doesnt make sense since I did that before.

Im not advanced with c++,So it might just be a very stupid thing that im overlooking or something.
