Maybe a bug in game review

I recently played a game with a bot and reviewed it. And it showed the Halloween gambit as a blunder, which was earlier just an inaccuracy and many of my other moves as great moves, also some of the responses of black which were earlier shown as excellent were now shown as mistakes or blunders, so is it a bug or some change in the review system, I have added the game below for reference, thanks.

I think it depends on the depth of the engine used.

At least it told you why. When I game reviewed against the knight bot, the coach said nothing.

Because you already use your daily review.

It is not a bug.The Hallowen Gambit is a blunder.If Black focus more in the position and with very good play,Black is winning.

How much the engine analyzes and what level of engine is

I am not sure which specific definition chesscom uses but as I have encountered it is the number of Plies (technical term for one move EG 1.E4 is ply 1) that the engine has considered. When I run stockfish on SCID vs PC the depth that I get is how far the principle Variation (typically the line that the engine thinks is the strongest) goes. although you can also use depth to look at how deep the overall search is by the engine, naturally with the explosion of a game tree you can't look at 100% of the positions that arise from one particular board state so some level of pruning (removing garbage lines) has to happen. At it's core the halloween gambit is a blunder because it is bad if the opponent knows the response. just because a move has the potential to win you a game does not make it a good move.

No I did not mean that Halloween gambit is not a blunder, I just meant that earlier when I used to review a game with Halloween gambit, it used to state it as an inaccuracy, but now it’s stating it as a blunder

It depends if you play another move,before the sacrifise,like Bishop somewhere and then you sac the knight.
