GetMovementBase() returning null ptr

I’ve been all over google and trying everything I can think of, but I’m at a loss.
I’m transitioning from Unity and trying to get the equivalent or rigidbodies. There does not seem to be anything in the add component.

I’ve attempted to call the Pawn constructor but that crashes the engine before it even finishes loading (I’ve read that in C++ the default constructor is automatically called, so that might be why).
Movement Base has the functions I’m famaliar with, such as AddForce, but GetMovementBase() tends to crash the engine. It also doesn’t show up in the inspector. I assume I have to add MovementBase somehow? I’m sorry to ask such a noob question, but I’ve been searching for days and I can’t find it anywhere.

Thanks in advance.

EDIT: I think I have a lead. Apparently I forgot to add a collider. My bad.
