I did clean install windows 10 and when i was loging into my Minecraft account with same...

... To add to the above. To eliminate that it was not a local issue on my windows 10 machine, I completely formatted the machine and did a clean install of windows 10 on another machine I had sitting around. After installed windows 10, doing all the updates,
and then trying to connect to minecraft through my xbox live account I received the exact same error message. This should eliminate that this is an issue locally on my computer and points more toward an issue with xbox live account perhaps?
Microsoft ... going to need your help.

That's odd. When you installed Windows 11, did you upgrade from Windows 10 to 11 or did you do a clean install with Windows 11?

I do not get an error message when I sign into my Microsoft account on the Microsoft website?
Windows 10 is up to date. I performed a
clean boot. The same problem occurrs in Minecraft - I cannot log in.

It seems that it was not the right account. Can you check on your MS account settings if the email address is the same as where you see the email that bought Minecraft?
