Edit, this time I did cut off my first next move, so I rather pasted full new output again, please take a second look, befor you copy and paste the wrong moves from my side this time

And I'm gonna have some sleep now, so you're even more not in any hurry, having accumulated 4 days already too
:)
Very good, so I'm gonna extend couple of moves from your PV just to speed up things:

Does Dragon 2.6 suffer from the same issue?
Fat Titz by Stockfish, the engine with the bodaciously big net. Remember: size matters. If you want to learn more about this engine just google for "Fat Titz".

Good Morning!
You don't really hope for getting the Queen captured here now still, do you?
:)
But you're right, I shouldn't always just give the next shortly pondered about line of Crystal's, I just still hoped, you'd make a backward of one of them and see your SF climb much higher than Crystal with the evals. Yet seeing SF again tempted to accept the sac, let's me doubt that more and more.
So this time just two moves more:

Crystal from clear hash see nothing after Qc2 and suggest Qb7 so I wonder if there is some hash bug or maybe a deep win for white.

Edit:I still believe that the plan Qc2 Nb2 and a4 should be winning for white and stockfish claims Qb7 is losing against b6 so crystal no NNUE is not so impressive.

That's why I gave Nb2 additionally, and even if I maybe shouldn't continue helping Milos by showing him, which one moves not to choose, here's my Crystal's output recently after 56.Qc2 Kb7 57.Nb2, of course not started with empty hash:

8/1kp5/1q1p4/pPpPp1p1/2P1Pp1p/P4PbP/1NQ3P1/5K2 b - - 0 1

Analysis by Crystal 251221:

57...Qa7 58.Qb3 Kc8 59.a4 Kb8 60.Qc3 Kb7 61.Nd3 Qb6 62.Kg1 Kb8 63.Nc1 Kb7 64.Nb3 Qa7 65.Qxa5 Qxa5 66.Nxa5+ Kb6 67.Nc6 Be1 68.Kf1 Bd2 69.Nd8 Ka5 70.Ne6 Kb6 71.Nxg5 Bb4 72.Ne6 Kb7 73.Kf2 Kb6 74.Ke2 Kb7 75.Nf8 Ba5 76.Ng6 Kc8 77.Kf2 Kd7 78.Nxh4 Ke8 79.Nf5 Kf8 80.Kf1 Kf7 81.h4 Kf6 82.Kf2 Kf7 83.Kg1 Bb4 84.Kh2 Kg6 85.Kh3 Bd2 86.Ne7+ Kh5 87.Nc6 Bc3 88.a5
+- (9.00) Depth: 43/82 00:33:04 82905MN

@ Milos: this now isn't meant anymore as for premoves, just to show, that Crystal's evals are still climbing, even if there's much too much shuffling in the line of course.
I just see, that letting Black hop in at the latest possible postiton just after some unnecessary extra- moves but before a relevant one, gets the whole thing really boring and long and I yet still hope to reach decisive advantage (for human eyes too) soon now interactively.
Only the moves up to last fen are already played from my side so far.

Good Morning!
You don't really hope for getting the Queen captured here now still, do you?
:)
But you're right, I shouldn't always just give the next shortly pondered about line of Crystal's, I just still hoped, you'd make a backward of one of them and see your SF climb much higher than Crystal with the evals. Yet seeing SF again tempted to accept the sac, let's me doubt that more and more.
So this time just two moves more:

2k5/2p5/1q1p4/pPpPp1p1/N1P1Pp1p/P4PbP/3Q2P1/5K2 w - - 18 56
