I think stockfish is slightly fixed now, it shows +M20 after pressing the forward or backward button
What’s wrong with Stockfish?!?!

This is very famous position, known as Queen's dance position. I have watched it many times on YouTube, where white Queens are dancing around black king, forcing the black rooks to cover the checks, until the black pawn goes to e4, and then white delivers checkmate to the black king by moving their queen to f7. Very famous checkmate, but unfortunately, or luckily, it is impossible to meet in a real game. I hope, I explained it understandable, and without any error in chessboard coordination

Stockfish missed:
Qb7+ Rc6 Qa5+ Rc5 Qb3+ Rc4 Qd2+ Rd4 Qf3+ Re4 Qg5+ e5 Qf7+
Re6 Qd8+ Rd6 Qb7+ Rc6 Qa5+ Rc5 Qb3+ Rc4 Qd2+ Rd4 Qf3+ e4 Qg5+ Re5 Qf7+ Re6 Qd8+ Rd6 Qb7+ Rc6 Qa5+ Rc5 Qb3+ Rc4 Qd2#
Stockfish sees the completely winning position (for white) below, and COUNTS IT as a DRAW?!?!
