likely that your hands are getting off plane, you are 'lifting and rolling' -go back to the 'twist away' move and get the club 'up' and outside your hands
keep the clubhead outside your hands until hip high, and work on short pitch shots.
The issue is that you are very likely using manipulated hands to square up the overly open and off plane clubhead. When you just let the pivot do the work, you are 'lagging the hosel' and not the sweetspot
Keep the clubface 'looking' at the ball on your takeaway using the twist away move, and 'hold the twist'
split grip drills are helpful here as well
