Xbox Elite Series 2 controller keeps disconnecting when I press and hold any button

I recently bought an Elite Xbox Series 2 controller for my PC, and I ran into an issue where every time I press and hold (edit: any button), the controller would briefly disconnect (no input, xbox button blinking slowly). It reconnects within a couple seconds, but a couple seconds is a very long time in reference to gaming, especially combat. I can't play the game without these two inputs, and I surely can't play it with the multi-second delay.

Any solutions?
