Gray Screen of Death (when opening blueprints_?

I’ve been working on a particular project for a while in 4.27. Starting to add wildlife - deer, wolves, birds… I have deer working just fine but suddenly can’t open the BP for my wolves. When I try, I get a giant gray screen ‘UNRECOGNIZED TAB’ with a ‘document’ tab in the top left. I close that and my BP tab appears as it should, but is all dark gray with no option to open the blueprint editor.

Someone suggested I delete the Intermediate folder in my project. I did that and allowed the assets to reload, but it didn’t resolve the issue. Anyone have any idea how to fix this?? Would really appreciate it.

I think this works in 4

In the main editor window:

Window → Load layout → Default editor layout

That worked!! You are a legend!
