Weird Reflection Scale

Well, good news bad news depending on how you look at it.
It works perfectly fine on my machine using default import settings for the FBX.
So it is most likely something specific to one of the materials or a project/post process volume setting.

Both the mesh and textures are normal. I just created very basic glass, metal and wood materials for this.
I’d start with re-importing the mesh, make sure you have the right UV channel selected for textures in the material and perhaps try testing alternative materials.

Edit: Oh, and in an unrelated note, your UV map appears messed up on the board between the middle and outer windows, causing a distortion.
