Please see the picture, what's the best strategy to fix this? The skin which is quite thick is peeling off but the back end is quote solid. I have stopped further water leakage.

Should I be cutting the dry wall piece and put another one or I can manage fixing it without that?

Should I rip of the nearest crown molding as well and put it back?

Or this project better left to a professional?
