I've got a couple of things to try. First, delete the personal saved data for NHL 25 with these steps. 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.
- Press the Guide button and then highlight the NHL 25 tile
- 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
Also, delete the local saved games with these steps:
- On your Xbox, go to Settings > System > Storage devices
- Go to Clear local saved games
- Hit yes
Try these and report back after playing again.
