Error while reading window layout

I had the following error when I opened a previously working scene: Error while reading window layout: window #13 is null UnityEditor.WindowLayout:LoadWindowLayout(String) Failed to load window layout: System.Exception: Exception of type 'System.Exception' was thrown. at UnityEditor.WindowLayout.LoadWindowLayout (System.String path) [0x0011f] in C:\BuildAgent\work\b0bcff80449a48aa\Editor\Mono\GUI\WindowLayout.cs:518 UnityEditor.WindowLayout:LoadWindowLayout(String) Failed to destroy editor windows: #7 ASMainWindow ConsoleWindow InspectorWindow ProjectWindow GameView SceneView HierarchyWindow UnityEditor.WindowLayout:LoadWindowLayout(String) Failed to destroy views: #12 SplitView DockArea SplitView DockArea DockArea DockArea MainWindow Toolbar SplitView AppStatusBar DockArea DockArea UnityEditor.WindowLayout:LoadWindowLayout(String) I've had this happen once or twice before and it's really annoying. Is there any way to recover my window layouts or do I have to build it all again from scratch?
