If there is a bug, the way to let the developers know is to file a bug report.
They do not generally read the forum.
I found a similar thread from several years ago:
https://www.chess.com/forum/view/site-feedback/there-was-an-error-classifying-the-move
Recently, I've been getting so many "There was an error classifying the move" errors when analyzing my games. Even more, the analysis page often takes minutes to load in the first place. I've ruled out any issues with my wifi. For months, I hadn't had this problem.
This is really unacceptable, especially considering how much we have to pay to access unlimited game reviews. Perhaps I'd be better served cancelling my membership and using another engine if this persists.
Chess.com devs, please look into this.
