Skeletal Mesh Completely Black on Import

Hey There UE Community!
So, Today When I imported a particular skeletal mesh in the editor (4.21), it was completely black, I tried switching the materials but it was still the same.
Although, When a placed a point light close to it, the textures were visible (although not too clear but you could see stuff written on it).
Does anyone recognize this problem, what are your thoughts on how to fix it?

Thank You for Your Help!
