My Mannequin is stuck in this position

I was following this tutorial: TPS Build Part 5 - Retarget, Adjusting and Creating Animations/ Setting up Aim Offset - YouTube
then My Character is stuck on this position.
can someone help and tell what is the issue here?

hi there !
this is the A -pose (default position of the mannequin when no animation triggered)
this can be because you have no animation blueprint in your pawn, or that the animation you set is not retargeted to this skeleton.
