Can you close those floating trays using the “x” button in the upper-right corner of each one? If so, go ahead and close them all, then use the View->Reset Workspace command to bring things back to normal.
If this doesn’t help, then there must be something funny going on with the files that LayOut uses to remember window positions and such. You’ll want to manually delete these files.
Close LayOut, open an Explorer window and go to this directory:
C:\Users{your user name}\AppData\Roaming\SketchUp\SketchUp 2016\LayOut
Delete all of the files that have the “.plo” extension, UserDockLayout.xml, and UserInspectorLayout.xml, then try running LayOut again.
Thanks,
