Hello thanh lo,
Welcome to Microsoft Q&A forum.
Since this is a public forum, we will hide your personal identifiable information, and I have sent that image of yours containing your personal identifiable information in a private message so we can work together to resolve the issue. Also, please check your private message in case you want to share another screenshot to avoid leaking your PII by click on the Private Message button.
Before we proceed further, may I have a photo of the error message when you try to play Minecraft online to check for you? Please remember to remove all personal information before posting. Also, may I know if this issue happens with any other Microsoft games?
I'm waiting for your reply.
