Disagree. Stockfish says 1. ...Kf6, 1. ...Kg6 and 1. ...Kg5 are all winning for black. Either continuation allows black to promote one of their pawns and win.

I’m kinda ashamed of using sf instead of raw skill, but can you point out a line that wins for black with Kg6 and Kg5?
As a 1500 player, i don’t really understand this 2600 rated puzzle

The position you analyzed was different. The puzzle started from the position you analyzed after both black and white played b5 and a5 respectively.
As for the line from 1. ...Kg6 or 1. ...Kg5, and 2. Ke4 Kf6 followed by 3. d6 Ke6 4. d7 Kxd7 5. Kxe5 Kc6 7. Kd4 b4 8. Kc4 b3 9. Kxb3 Kb5. At this stage, black will capture white's a-pawn and promote its pawn. White's f3 will be met with ...gxf3, while f4 is also met with the en passant ...gxf3, eventually promoting. Of course, I didn't get the full line all by myself, but after the first move, all moves were somewhat forced to prevent white from promoting its passed pawn.

Yeah it will be removed for sure.
My guess is that when this puzzle was generated it was analyzed with a weaker SF than now so at the time lines were different.

Oops, mistake on my side
I now see that all three continuations win for black, after analyzing at depth 70
