Unity 5.4 Scene Tab Broken

Ok, So I was Building My Game, when I started getting errors preventing me from Playing my Game, the Errors Mainly being repeats of “SUCCEEDED(hr)”. So I Restarted Unity and Now My Scene Tab Is COMPLETELY Broken, Displaying Nothing, Even when I reset the Layout to Default, as Well as other Layouts.

I Cant Even Click other Tabs Alongside the Top By Scene, However, When I use a Layout That Seperates The Scene and Game Tabs, The game Tab Functions Normally.

The Console Has These Errors, all repeats of the same thing:
NullReferenceException: Object Reference Not Set to an Instance of an object
UnityEngine.GUI.Toolbar (Rect position, Int32 selected, UnityEngine.GUIContent[] contents, UnityEngine.GUIStyle style) (at C:/buildslave/unity/Runtime/IMGUI/Managed/GUI.cs : 968)

I Don’t Know Why This Is Happening Nor How to Fix it Please Help!

Ok So I Eventually Got it to Work, If this Happens, Just make it so that unity doesn’t load the scene tab on startup. What I Did was I Brought the Console Up to the Middle Tab Area, then Made It Fill The Whole Screen(Till Only It And The Scene Tab Exist.). Then, I Restarted Unity (was Turning it off to Post this Whole thing) And It Loaded the Console Before the Scene Tab, then the Scene tab Worked.
