Help Rope Cut not working

[kripa1415]

Hi,
 I've attached video reference here of what happened while trying to cut the rope.
 I've used RopeSweepCut. Its working in the sample scene. But If I use the same script for my Rope which is created dynamically at runtime, it not working.
 When I swipe to cut, I can see the line renderer and on release, there's a shake happening in rope but its not actually cutting the rope.
 I added log inside the below function. Log printed as expected but cut doesn't work

Code:

private void ScreenSpaceCut(Vector2 lineStart, Vector2 lineEnd)
{
    // keep track of whether the rope was cut or not.
    bool cut = false;

    // iterate over all elements and test them for intersection with the line:
    for (int i = 0; i < rope.elements.Count; ++i)
    {
        // project the both ends of the element to screen space.
        Vector3 screenPos1 = cam.WorldToScreenPoint(rope.solver.positions[rope.elements[i].particle1]);
        Vector3 screenPos2 = cam.WorldToScreenPoint(rope.solver.positions[rope.elements[i].particle2]);

        // test if there's an intersection:
        if (SegmentSegmentIntersection(screenPos1, screenPos2, lineStart, lineEnd, out float r, out float s))
        {
            cut = true;
            rope.Tear(rope.elements[i]);
            Debug.Log("cut");
        }
    }

    // If the rope was cut at any point, rebuilt constraints:
    if (cut) rope.RebuildConstraintsFromElements();
}
