Dear friends,
When I'm in reder view mode, there are lots of extra lines (like it's a wireframe) and strange artifacts on the model.
artifacs visible at the left:
Under this arfifacts, even the texture is not visible (in Cycles, in Eevee it's more or less ok).
Why is it so?
That's weird. Could it have something to do with the fact that you imported this model? (Did you use Collada (.dae)?)
I only use Blender, so I do not know anything about importing and exporting, apart from fearing it;)
(Hopefully USD will improve the situation.)

I'm proud to be a dear friend haha.
Is there a chance that you have modified the WireFrame settings in the Viewport Overlays?
I get similar results when I play with that. Usually I have it turned off completely.
