Side-way views (editor) do not render anything for my block out world

Hi all!

New to the forum here and looking for some… fairly newbie advice I reckon. I am blocking out a level for my third person game and I’m running into an issue with the perspective.

I’m not sure what’s going on but the issue seems to persist - some setting is probably off somewhere, but I don’t even get a grid in my non-perspective views. This is a rather fresh project I’ve created so don’t know what I’ve broken. Getting the same thing across two machines.
