Can't log in My Steinberg

My friend upgraded & installed Cubase13Pro yesterday
And he tried to long-in to “My Steinberg” then asked Two-Step verification
He tried with Microsoft Authenticator but unfortunately, maybe his phone doesn’t work correctly
then that’s his bad but he clicked “next”

so he lost QR code already

it means his “Microsoft Authenticator” doesn’t recognize his “My steinberg”
now he can’t long-in to My Steinberg and he can’t do anything

How he can solve the problem and log-in My steinberg?

Does anybody know the solution?
