The grip is quite strong, causing a closed club face bias. The blocks likely stem from your reverse pivot and cupped left wrist, which inadvertently open the face. The real issue, however, isn’t your setup but rather the heel impact. This gives the illusion of a closed face, when in fact it’s more like a shanked baseball foul ball—low and right. We need to work on standing taller, limiting backswing, and keeping your hand path more inside to avoid ‘heelish’ encounters. Remember, golf is a lot like taxes—you drive hard to get to the green, but end up in the hole. Keep practicing!
