The knight has a great square on d4, while the bishop is restricted by its own pawns. But Black has a protected passed pawn, and White a backward b pawn. The analysis engines Stockfish12 and Komodo11.01 reckon the position is dead-equal.

41.h5??
The engines' evaluations had not wavered from dead-equal, until this losing blunder.
41...Ba6+ 42.Ke3 gxh5 43.gxh5
The h5 pawn is very weak, and if White tries to protect it the d pawn advances.
43...Bf1 44.Nd4
No better is 44.Kf2 Bh3 45.Kg3 Bf5.
44...Bh3 45.f5!? Bxf5 46.b4+!? Kxb4 47.Nc6+ Kxa4 48.Nd8 Kb3 49.Nxf7 a4 50.Nxh6 Bh7 0-1
