Login to Microsoft/XBOX-Account is working fine on Nintendo Switch and a physical Windows 11 machine plus virtual Windows 11 machine (running on HyperV on Windows 11 host - another physical Windows 11 machine).
But on the Windows 11 host itself login was NOT possible. Several uninstallations (of Minecraft Launcher + Minecraft Bedrock) and re-installations were not helping.
Finally, I got it fixed while manually activating "Xbox Live Auth Manager" service. On the other Windows 11 devices, this service was running by default. I have NO idea, why it was not running on this single machine.
Btw.: Login with same account on same machine in Minecraft Launcher was possible. Entering Bedrock from the Launcher... login was failing. Entering Minecraft app directly... login was failing.
