Problems with Vertical Fov cutting off the edges of the render

[LennoxGL]

Persistent bug in eeVR Vertical Fov.
Render engine: Eevee
I'm using Blender 4.2, but I'm having the same bug in lower versions.
Latest version of eeVR, rendering in PNG, without stereoscopy.
Render resolution at 1500x1128, but I had the same problem at other resolutions

Settings:

I want to make an equirectangular render, at 180 degrees and resolution 1500x1128, but without the top and bottom part of the render, only the horizontal part of the render, like this: (made in Cinema 4d, resolution at 5800x1080, vertical fov at 90 degrees.)

For this, I suppose I would need to set the vertical Fov to at least 90 degrees, but when I do that, the edges of my render disappear, leaving it like this:

I've already done several tests, changed the parameters, the addon version, the render resolution and the blender version, but nothing worked, the Vertical Fov always leaves my render like this, regardless of the project or the blender version.
Always in parameters below 180 degrees, this happens. I tried changing something in the Front View Fov too, but it also had no effect, apparently it didn't even change anything in the final render.

(same render, with Vertical FOV at 180 degrees)

I haven't seen anyone with the same problem, and I've actually tried a lot of things to try to fix it, but I have no idea what's going on. Does anyone have any ideas? I tried to contact the addon dev directly, but he himself recommended that I post here.
