Hi Support

I have a problem with my username to login to "Minecraft: Java Edition".

I purchased Minecraft in the MS-Store. To start the game I use the "Minecraft Launcher App" (v2.1.3.0). I can login to the "Bedrock Edition". But when I want to start the "Java Edition" I have to set a username -> see the screenshot. My name is already used. But I'm very sure, that nobody else uses this name. What can I do to resolve the problem?
Thanks for your help.

Regards
Marco
