UWP fails to sign in to xbox live

Question

I asked the same question before, but I didn't get a reply, so I'll ask again.

I'm developing a UWP game using Unity. The version is 2019.4.26f1
The target hardware is PC and Xbox One.
The following phenomena are occurring in both.

I'm having trouble signing in to Xbox Live when signing in in-game.
I succeed in Microsoft account signing in after launching the game, but then fail to sign in to Xbox Live.
The content of the error is "The application requesting the authentication token is disabled or not configured correctly."

When I checked the sign-in status, it seems that the status is returned correctly only at the time of cancellation.

I have confirmed that I can sign in with a test account using the companion app on my PC.
The sandbox switching has also been successful.
We also released the results.
I don't know what caused it.
Thank you.
