Game Crashes on Open Level Node

Something new has started to happen… while in the editor, when I click to load a map - on load of said map - it shows a blank screen (black) in the editor (no grid) as if there is nothing on the level. This however is untrue. Zooming in and out or scrolling around will not allow me to find anything. But if I go to the world outliner panel and select any asset, it brings the level up as it should have from the beginning… very confused here…
