I've been experiencing this bug since the release of iOS 15. Still exactly the same. The keyboard "appears" transparent (still tappable). Accessibility Settings solution works (not sure if 100%), but it's not a solution, to destroy great (animated) experience to solve a keyboard bug. Apple, please fix it ASAP. It has been too long already.
