Viewport Becomes Black in Orthographic Projection

When designing levels using the Viewport, or when Editing Assets, whenever I switch from Perspective to any of the Orthigraophic Views such as Top, Bottom, Right, Left and so on, the View becomes Black, even when the Rendering mode is set to Lit. Is this a Bug? Or Am I Missing Something?

Did you ever discover a solution or root cause of this? I am all of a sudden experiencing same issue in 4.26.
