Prefab mode doesn't show prefab, still shows old scene.

I keep running into this glitch, and other people on our team have run into this problem as well, but I can't seem to see a single person reporting it. It's EXTREMELY annoying, as you can't edit prefabs after this glitch occurs, changing scenes doesn't seem to do anything for it.

Basically, if you're editing and the scene is all normal like this: https://prnt.sc/qlyfeq

But when you double-click a prefab, it attempts to open edit mode, but still seems to not do anything. http://prntscr.com/qlyhfp

As you can see, it's selected and the gizmo should be showing, but the old scene is still there, and no gizmo is showing at all, and if I press f it zooms in on an empty point in space, presumably where the prefab is? I can even still select the objects in the scene that I shouldn't be seeing.

I don't have anything selected as the prefab editing environment either, and setting it to be something didn't change any behavior.

This is very annoying, oh and I'm running Unity 2019.2.17f1.

Any help would be appreciated.
