Why Can’t I ready up or choose position

Try clearing your alternate MAC address with these steps:

Go to your Xbox Settings
Go to "Network", then "Advanced Network Settings"
Click on "Alternate MAC Address", and then click "Clear"

Also, it might be good to delete your personal saved data for NHL 23. To do that, press the Guide button and then highlight the NHL 23 tile. Then, hit the Menu button. It's the small one to the right of the Guide button with 3 horizontal lines on it. Next, go to Manage game and add-ons > Saved data. Delete the file with your gamertag on it. There is the risk of losing offline saves and changes to settings you've made. Normally, those download from the cloud, but I can't guarantee this. Let me know what happens. Thanks!
