Minecraft Bedrock on iOS faits Microsoft account sign-in with Error Code: Tuff

Short description of the issue

Minecraft Bedrock Edition on iPad cannot sign in to my Microsoft account and shows Error Code: Tuff.

Steps to reproduce the issue

1. Open Minecraft Bedrock Edition on iPad.

1. Try to sign in to a Microsoft account.

1. Minecraft fails to sign in and displays Error Code: Tuff.

Expected result

Minecraft should successfully sign in to my Microsoft account.

Actual result

Minecraft cannot sign in and displays:

"Failed to login"

"We could not sign you into your Microsoft account."

"Error Code: Tuff"

I have tested the same Microsoft account in Safari and in the Xbox app, and it works there. The same Microsoft account also works in Minecraft on another device.

I have already tried restarting Minecraft, checking automatic date and time, using both Wi-Fi and a phone hotspot, changing my Microsoft account password, reinstalling Minecraft, and signing in again through the Xbox app. The problem still occurs on the iPad.
