Looks like this white to play and draw is cooked, in the main line it looks like black can force a win on black's 5th move by playing 5...rd2 or 5...re2 or 5...ra2 instead of 5...rf1.

Eval was higher at the end of the Backward first as you see, but it's dropping more and more to rise then again with longer pondering on 32G hash and it takes longer and longer for next iteration to solve fail low.
6men Syzygys but NNUE- usage off, won't help as for the necessary search here I guess, maybe it was even better to switch off tbs.
Output's not proving to me neither, maybe I'll let it play out SF against Crystal, till then I'd rather think the study to be correct yet,
regards
Peter.

Both engines had 15 threads of 16x3.5GHz CPU and 8G hash, 6men Syzygys.
So you yet might have found another cooked one indeed,

Thanks for pointing out the one already discussed Peter. Here is another one that hopefully wasn't discussed before that Stockfish thinks is cooked. White to play and draw, but in the main line Stockfish says black should play 2...Kd6! and gives a winning eval.
