FBX Animations, keyframes not importing / Not resolved

Hello everyone ! I was trying to importing a FBX animation for my skinned mesh, but when importing it, no keyframes is imported… This issue is happening with every skinned meshes.

Update : It don’t work on my skinned mesh which have over 60,000 triangles

Update again : I can import other meshes animation on it, ONLY this skinned mesh’s animation won’t work…
