NavMesh and RigidBody

Hey ! So I 'm currently stuck while trying to navigate some characters up to a point with navmesh (Also have Rigid bodies with frozen Rotation) . On destination I set Nav Mesh Agent.enabled = false. Then apply force to imitate walking and play an Animation (Walk) and right at that transition I get a micro stutter in Unity but it works fine until I build and Run which at this point my characters disappear off scene.
(Rigid body is not kinematic and have tried Animation Culling Mode : Always Animate)
Any idea what might be causing this issue ?

Okay so I tried switching Rigid body to Interpolate and Collision Detection to Continuous which seems to work fine!
