    Same problem here (Unity 2017.1.0f3, Win10 [resettet my OS 2 weeks ago from win8 to win10]).
    Last 15 times it happens after changing some .cs when pressing the Play button (between 3h and 30min). But 1 time (last one) it happend after i drag and dropped a prefab from an other project to my project, then i grabbed the prefab in Unity and wanted to drag and drop it into the hierachy, but after dragging it it crashed.

    I keep getting this occasionally too. I will press play, the dialog box appears, I click Quit and...well you can guess what happens next. Windows 10, Unity 2017.1.0f3. I'm glad I have an autosave asset so I don't lose any work.
