My model turns black

Hi. I wanted to start making a game and I made my 3D model and everything and I also exported texture for that model. I actually made it few years ago and it worked perfectly fine. I still remember it. But when I installed unity again and when I try to import same model and texture for it,it just turns black. I was searching for answering everywhere but I couldn’t find it. Can anyone help?

Maybe unity doesn’t support that model anymore? Try installing the old version or something like that and testing it out or it could also be the model it self, try making a new one.
