As given, both black and white pawns must have made 4 captures - so
all missing pieces, including wRa1 and bRh8 were captured by pawns.
Therefore, last move cannot have been PxN=N, but PxR=N.

But after uncapturing a rook on g8/b1 thze black/white king is
locked and can never leave his prison.

A typo or did you just overlook this?
