Screens freezes and turns black on changing layout in Unity editor,I am using Unity for the first time and when I try to change the layout by dragging or resizing, the screen turns black

I am trying to change the layout of my Unity and it just turns black and freezes.Restarting the application or system doesnot seem to sort this out. Please help as I need to start on a project.,I tried dragging hierarchy to the right in Unity editor and also the Game panel. However it just turns black and freezes. Restarting does not help, reinstallation of software also doesnot work.
