my minecraft game says that '' You can't play on realms because of how your microsoft account is set up. Please ensure your online safety settings allow Multiplayer and clubs. See instructions for changing these settings at aka.ms/MCMultiplayerHelp.''

I have been trying my very best to try and fix the issue, but none of my ideas work. Once it took me to a website to change my account from kids to adult. But I do not know how to do it. I am not a kid. I am an adult. So please I need help as fast as possible.
