Windows 10 Minecraft will close itself when I sign in to my xbox live account

No, sorry maybe I posted in the wrong section. This is a PC with Windows 10. When I saw "Xbox for Windows 10" I assumed that was referring to the Xbox Live thing I signed into on my Windows 10 PC when I played Minecraft.

You can sign on with your Xbox live account on Minecraft windows 10

From 2017, probably still relevant. See post three on this Minecraft forum:

Windows 10 Can't Sign into Xbox Live

Solution to the problem with your account used in Windows 10:

• Search the '' Xbox Identity Provider '' application in the Microsoft Store;

• Verify that the app is installed and up-to-date;

• If persist in making the app error, create a new user account on the computer.

• Download Minecraft

• Sign in to app Xbox with the account you used to purchase Minecraft

• Log in to Minecraft and access Xbox Live through the game.

• Sign out of your new account, sign in to your account and sign in and play on Xbox Live.

I'm having the same problem. I can get online. My avatar shows I'm signed in but when I go to the store (Minecraft) it says I need to create an Xbox Live account. When I go to Xbox Live signup it says I'm already signed in. When I try to create an account
using my Windows and Xbox Live account info it says the credentials are already being used (by me).

Part of the problem I'm having is when I'm signed in with the Avatar, I don't know if that's the windows live account or the Xbox live account or something else. I doesn't say, which is not helpful. I can log into both windows and xbox live on my computer.

How do I associate my gamertag with my Xbox avatar? Or, if that's not the issue, how do I resolve this?
