Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Enable the Cameras overlay in the Scene View
3. Enable the "Control a camera" mode in the Cameras overlay
4. Enable the Isometric perspective
5. Move the camera around with right-click
6. Return to Scene camera (Disable the "Control a camera" mode in the Cameras overlay)
7. Observe the Scene View

Actual results: The Scene View is gray and nothing is rendered in the scene

Expected results: Everything is rendered properly the same as at the beginning of the reproduction

Reproducible with versions: 6000.2.0b2

Not reproducible with versions: 6000.0.49f1, 6000.1.4f1, 6000.2.0b1 

Tested on (OS): macOS Silicon Sequoia 15.3, Ubuntu 22.04, Windows 11

Notes:

• When moving the camera around in step 5, the perspective icon in the Scene View is jittering
• Restarting the Editor does not fix the issue
• Closing the Scene View and reopening the Scene View fixes the issue
• Creating a GameObject after step 6 throws an error:"Invalid worldAABB. Object is too large or too far away from the origin."
• The MainCamera position is changed to very random numbers, resetting the transform does not fix the issue
