    I've got the same problem in Unity 6000.0.11f1

    Progress bar => full
    Window title => Importing (iteration 2) (busy for 50s)...
    Below progress bar => *.shadergraph file path

    I could wait and wait and nothing happens.

    This shadergraph is not so complicated.
    If I go to this file in Files Explorer and change it's name. It un-hangs Unity editor. Then I change this file's name back to what it was and I can continue my work.
    Shader in this file also works ok.
    It doesn't happen all the time.
    Usually when I save a script in Visual Studio and go back to Unity Editor.
