Why do my objects with textures disappear in Blender when I put "Material Preview"

Hello, I have a car model, which is fully finished and theoretically correctly textured, but when I put the “Material Preview”

Simply all objects with those textures become invisible.

I need to know how to solve this problem, as soon as possible.

The image on the left is “Material Preview” and the one on the right is “Solid Preview”:

Hi there.
It may be helpful to see the material setup (including opacity settings)

Surely inverted normals and backface culling.
