Just loaded Blender 2.91.2 and the object in question is a small table (size x 240mm, y 150mm, z 230mm) and clip start settings are 0.001mm and clip end settings 100000mm.
Furthermore, if I zoom out until the object is just before the vanishing point (but I can still see its presence) zooming in doesn't work.
I don't know if this is a bug with this version or perhaps I have some settings wrong. Any help would be appreciated.
