I just played a game where in the end the opponent had a winning position but ran out of time and Chess.com determined that it was a draw because of Insufficient material and the opponent had a queen. I am sending the link: https://www.chess.com/analysis/game/live/138515661760?tab=review&move=134
There's no error. Your opponent has no time and can't win. You didn't have sufficient material to win on time. You only have a king and can't mate given infinite time so the best result is a draw
