After login into windows 11 the Microsoft sign in page went blank

[Guest Timothy Shao]

After I start my computer and safely pass the login screen and successfully land on desktop everything is functional but after a few second the window that usually tell me to login into microsoft account just went blank, by blank I mean just a window without any press able things beside input indicater, accessibility, and volume. The worst thing is this thing blocks me access any other features, I can do ctrl alt delete to open taskmanager but the login window just blocks my whole desktop. I still finding ways to solve this hope I can get some help here.
