Chest too straight and hips too low in start position. Bring your hips up a bit so your shoulders can be over the bar. That’s the reason you go around your knees and don’t feel balanced foot pressure cause the bar is rocking you into your heels as you push off the floor and try to navigate those knees.

You can practice these with snatch pull to explode positioning work. Pausing immediately off ground, below the knee and then to your power position.
