The game won't allow me to login. It gives me codes then the "signing in" screen pops up and then nothing happens.

It won't let me login to my Microsoft account on Minecraft. When it does let me login, I'm able to play for a while but if I exit out of the game without saving then this issue occurs and I don't know when it'll let me login again. I can sign onto the Microsoft account on my phone just fine, and my brothers account works fine to. So idk what's wrong with it.
