4 Camera View - TOP view not working

Dell XPS 8960 / 32G Ram / 13th Gen i7 / NVIDIA GeForce RTX3070

Hey crew. Looking for some help here. I'm using 3d layers and camera to create a close/far rotation effect, and it would be great to utilize top view to build these keyframes in the comp window. BUT for some reason, Top View refuses to show my layers, or my camera. It's just a black screen. All other angles, (Active, Right, Front) work perfectly. It seems like a weird glitch, and it has worked in the past, in this project. Here's what I've tried:
- purge cache memory in the preferences dialog  - manually deleting user libraries / presets in My Docs- manually deleting AE Cache files in AppData/Roaming- Reinstalling A.E.(vers) 24.2.1
- updating GPU drivers (NVIDEA studio driver) 
Any ideas?? I'd love for this to work.
