Stockfish 17 says mate in 10:

34. .. Rxg4+

(34. .. Rxg4+ (1. ... Rxg4+ 2.hxg4 Rxg4+ 3.Kf1 Qb5+ 4.Ke1 Re4+ 5.Kd2 Bg5+ 6.f4 Bxf4+ 7.Kc3 Qxe5+ 8.Kc2 Re2+ 9.Kd3 Qe4+ 10.Kc3 Rc2+) +M10/73 32)

Sep-12-24  King.Arthur.Brazil: It is a quite direct attack: 34...Rxg4+ 35. hxg4 Rxg4+ (36. Kh2 Qg2#) 36. Kf1 Qb5+ (37. Rd3 Qxd3+ 38. Ke1 Re4#) 37. Ke1 Re4+ 38. Kd2 Re2#. By refusing: 35. Kf1 Qh1+ 36. Ke2 Rge4+ 37. Kd2 Bg5+ 38. Kd3 Red4+ 39. Ke2 Rc2+ 40. Rd2 Rcxd2# or 37. Kd3 Red4+ (38. Ke2 Rc2+ 39. Ke3 Qe4# ) 38. Ke3 Bg5+ 39. Ke2 Rc2+ 40. Rd2 Rcxd2# or even 38. Ke2 Rc2+ 39. Rd2 Rcxd2+ 40. Ke3 Qe4#.

The uneasy part of pot is to be wise that W♕ already dominates the squares f3 and c4, which cannot be used by B♕ for attack.
