Problem with my name, my skin and my Microsoft login

When I open minecraft bedrock my account closes and I have to reopen it, when I do my skins, layers and everything disappear apart from the fact that my name is changed to "SkinStandarCust" which is annoying since in private worlds I appear like this, On top of that, I don't have access to the capes they've been giving away lately even though I managed to claim them two days ago.

excuse my google translated english
