At this current point, no. NBA 2K23 is not currently available on Xbox Game Pass, meaning Xbox players will have to pay the full $60/$70 asking price if they want to play the game at launch.

Your first stop should be checking the server status for NBA 2K23, which can be done via NBA 2K website. If things are fine on the server side, then troubleshooting can be done on the player’s end.
