When starting the game, after following the "press any button" prompt, game hangs for upwards of 10 min with spinning block in lower right corner.

Attempted to restart both game and Switch system and neither resolved issue.

To reproduce: follow button prompt at start of the game.

Also, there’s a possibility this is related to changing my Microsoft password earlier today.

update: this is definitely related to Microsoft account password changes. I was able to resolve with the below steps:

1. Put your switch into airplane mode
2. start the game (it should boot up and give you a warning about turning off airplane mode for online options)
3. go to the start screen and open the options
4. Select game > configure online play > sign out of your Microsoft account
5. close the game
6. turn off airplane mode
7. start the game again and sign back into your Microsoft account with your new password
