Club face control.

So, after a few weeks of hitting the ball spectacular, I’m now struggling with inconsistency in my club face. in my back swing my club doesn’t feel secure at all, and i also feel like I have zero control in my grip. I’ve tried changing my grip multiple times to feel what it’s like to be square, but hasn’t helped. I’m not sure what I’m doing wrong, but at the top of my backswing, my club feels very “wobbly.”
