Why a quad appears on my render image

When I render with (F12) this white square appears in the lower left corner and I don’t know how to remove it.
Can anyone give me some tips?

Thanks

There’s no cubes or planes hidden in the viewport but not the render?

nothing. Just the model, camera and light.

Would you mind to share your .blend file?

Oh. Thanks. Here it is.

There is no problem with rendering.
After installing the new camera, try rendering it from a different angle.
Whether the same problem occurs.

Hi, there is no polygon/quad when rendering your same file on my machine?
