Weird Grey Box Around Model

Probably a super simple fix, but what is this grey box and how do I get rid of it? It seems to be tied to the Model as hiding the Model also hides the box. I spent hours combing forums for answers and the closest I got was Texture Space, but that didn’t end up being the cause.

I’m at a loss.

First i thought of Camera → Viewport Display: Passpartout but this jas a sharp border (or is their a blue featire in 4… ??)

Hi, could it be something in the material shader volume maybe??

Can’t say I even know what Passpartout is, but this is from the main camera, there are no camera objects in the scene.

Not that I’m seeing.

The greyed out area outside the camera view:

if you look closely in the grey area there are diagonal lines that might give a clue to were its coming from? Also a full screenshot of your setup in the outliner will be helpful.
