chaos vehicle not moving when animation is playing

hi
im having trouble with the chaos vehicle not moving when i press the key to play animation that i imported from blender. its a wheeled loader , i created the movement with chaos vehicle, and just added a animation when a key is pressed to lift up the bucket, the vehicle moves as intended before pressing key to play animation, but as soon as i press the key to play the animation to lift the bucket the wheeled loader cannot move anymore, any ideas what might be wrong?
