Puzzle from one of my games!

This is from a game I lost: Try to find the solution!

(this is the first puzzle I have made. If there is anything bad, please tell me!)

The solution works and most human players would probably select it but there are others of about the same value. Most obvious is a variation on the second move. 23. .. .Nf3+24.Bxf3 Rxe5 has about the same engine evaluation score. Also 22. ... Rxd5 should be a comfortable win.

The problem is that puzzles fail when engine scores are close. You can't expect a human solver to distinguish a score of -5 from a score of -6. Strong players will then choose the line of their personal liking and engines may change their mind over time when a newer version arrives.

So the weakness of the puzzle is not that your solution is wrong but that there are too many good solutions. A good puzzle features a solution where just one move is clearly superior to all the others on every turn and they stop before there is choice. That makes solving doable for a human. Otherwise he starts guessing which we call gambling, not solving.

Btw, such issues are predictable when you start a puzzle from a rook up position which almost always permits viable alternatives.
