Horrible loss for white.
It looks like black has a fortress.
If white king goes queenside then black recycles the king to a7 which frees the black knight.
Otherwise the black knight covers e4 from c5.
White seems to have played with the misconception that he could penetrate on the Q-side and do something with his b-pawn. Not only wasn’t that possible, but he left his K-side pawns in the lurch. 71.Kb5 looks like the losing move.
The diagram is a dead draw. White blundered badly.
