why bishop promotions ?!
If black plays 6. ... Kh7 then white is stalemated. If the bishops on d8 and f8 are queens then white loses! Blacks threat is 7. ... Rxd8+ 8. Kxd8 Qb8# and there is not much white can do about that.

Nice Study but why not Rxd7 and play on? I t still looks good for black.
It's tablebase stuff. the only way forward for black is to allow the exchange of his knight for a bishop. After that the position is a theoretical draw (even without pawn h5).
