Normal map turns black even after clicking fix now or the fix now doesn't even come up

Need help. ( I don’t know if I ask for help here )

I’m making a vrchat world and when I put the normal map into the normal map area it turns my model black. And it still stays black even after clicking fix now or sometimes the fix now doesn’t show up at all and it stays get black.

without the normal map

with the normal map in the normal map box

Does your model have both normals and tangents? A normal map only makes sense in the context of a tangent space (defined by the normal and tangent vectors).
