White has a slight edge, according to the analysis engines Stockfish12 and Komodo11.01.
24...Bb5 25.Ne1!
This somewhat anti-intuitive move is better than giving the bishop more range with 25.d4 Bd3.
25...Kf8 26.Kf2 Ke7 27.Ke3 Kd7 28.Kd4 b6 29.Nf3 h6 30.g4 g6 31.h4 Ke7
White is better - winning, according to Stockfish12, although Komodo11.01 gives only a slight edge. The latter is almost certainly right. One tell-tale sign is that Stockfish12 reckons White's advantage is worth 1.54 pawns whether White's next move is 32.g5, 32.Ke3, 32.b3 or 32.Kc3.
32.h5?
But this changes everything. Komodo11.01 reckons Black now has the upper hand (changing after time to just a slight edge), although Stockfish12 rates the position as equal.
32...gxh5 33.gxh5
The white h pawn is a fixed weakness on a light square.
33...f5 34.Nh4
Not 34.exf6+? Kxf6, when Black is almost certainly winning.
34...Be8 35.Nxf5+??
Unnecessary desperation. After 35.Ng6+ Bxg6 36.hxg6 Kf8 37.Ke3 Kg7 38.d4 Kxg6 Black is a pawn up but there is no way, as far as I can see, to make progress.
35...exf5 36.Kxd5 Bxh5 37.e6 Bg4 38.d4 h5 39.Ke5 h4 40.d5 h3 41.d6+ Ke8 42.Kf6 h2 43.d7+ Kd8 0-1
