Hey there. Unfortunately, there's not much we can do if the save file is corrupt. You can try the steps below, but I'm not super optimistic this will fix it.
If on XBOX:
- Hit the Guide button on your controller
- Highlight the NHL 23 icon
- Hit the Menu button. It's the small one to the right of the guide button with the 3 horizontal lines on it
- Choose Manage game & add ons
- Go to Saved data
- Delete the file with your gamertag on it
If you're on PS:
Go to Settings/Storage/System storage/Saved Data. Locate NHL 23 and delete the saved data.
Good luck! Hopefully, this helps. Unfortunately, if it doesn't, I don't have any other suggestions.
