Broom trial error???

[graceful idol]

I was in the middle of trying to beat Imelda's broom trials and all of a sudden my screen stopped completely. My immediate reaction was trying to see if my controllers disconnected and my controllers are completely fine. I tried turning off my switch and the screen is still the same. I don't know what on Earth is going on... Can someone please help...?

Broom trial error???

Is there a way to hard reset it?

I just restarted the console by holding the button down for a minute

And I guess everything is back and working

Still can someone explain what and why happened
