Mark the 3D layer option for any of your layers. Then, on the bottom right of your composition panel, you will be able to deactivate the 2 Views options. Then, revert your 3D layer to 2D.

You can also right click in the Comp panel and choose a single view. 

You can also double click on a workspace to reset it or go the Window/Workspace/Reset Current Workspace.
