This can happen if you have mirrored UVs.
Go to the mesh object properties and enable Fix Mirrored Tangents. Be sure Tangent Space is set to Mikk as well.
If that doesn't solve it, try offsetting the mirrored UVs 1 unit in UV space and re-exporting the mesh.
I t works ,Thank you ! Just enable Fix Mirrored Tangents,and change Tangent Space to Mikk
