Black is winning, but only one move will do.

42...Ke6
The natural-looking text sets a trap, but the analysis engines Stockfish12 and Komodo12.1.1 point out that winning is 42...Bd4!, trapping the knight. If 43.Nc5, then 43...Bxc5 44.Nxc5 Ke6 45.Ke4 a5 wins. White can try 43.Nb8, but then 43...Ke6 44.Nc6 Kd5 wins either the knight or the b pawn.

43.Ke4??
An extraordinary oversight. Also losing is 43.Nf8+? Kf7 (43...Ke7 44.Nxh7 Kf7 also wins) 44.Nxh7 (44.Nd7 Bd4!) Kg7, but 43.Nxb6 axb6 44.Ke4 draws.
43...Kxd7 0-1
