Xbox User selection in Launcher.

Xbox Login prompt when starting Bedrock.

Game loads to 97%, drops to some 70%, idles some seconds, loaded.

User is not logged in.

Trying to login from the Settings > Account page results in “Drowned”.

Entering Windows Flight Mode and enabling network again, one can login from the Settings > Account page / click on login and is logged in directly.

No issue with that in the previous version.

Affects only 2 of 3 Windows 11 devices we have. These two use children accounts under parental control and worked seamlessly before the lasted update.
