Your suggestion to remove all ties to xbox live in Credentials manager worked.

After removing all lines with Xbox when I clicked login in Dungeons Launcher the Xbox sign in poped up and I was able to login.

Thank you for your help and hopefully this will help in development also.

Bug can be closed.

Thanks

I dont think this is a duplicate of MCD-652 as I did not change my username in Xbox Live. Also after system restore from 2 days before I received Minecraft Dungeon beta invitation I have Installed the Launcher and it did not ask me for creditentials and just gave me an error Login failed, try again - same as on the screenshot.

There seems to be some issue between Launcher and signing to Xbox account? But As I said all other Mojang Minecraft games works fine and Xbox companion works fine.

I think the only thing I didnt try is full system wipe and reinstall Windows.

I am logged in as a main admin user with my Microsoft account. Microsoft store works, Minecraft windows 10 works. Minecraft Java works. Xbox Concole Companion works fine.

Its weird that I do not get a sign in window in the Minecraft Dungeons Launcher but after clicking Green button - Login - few seconds pass and I get Login failed, try again.

I have tried logging in on my friends PC and I can login no problem... something must be wrong with mine but what and why did it work before and now is not...

frustrating.

Now I even went and Restored my system to 2 days before I even got the invitation for Beta and installed the Launcher now and same thing. After clicking Login iget Login Failed please try again..... weird it did work on the day I got the invite for beta

I have tried your solution to uninstall the game and delete the "HKEY_CURRENT_USER > Software > Mojang > Minecraft Dungeons Launcher" in the registry but after rebooting and installing the Launcher again when I get to screen when I see green Login button - I click on it and I get Login Failed, try again - I even didnt go to the screen where you type the creditentials.... so the launcher dont know my login details and still giving me the error.

Its so annoying...
