Check Velocity and stop Velocity so Object does not bounce.

Hello,

The below code is suppose to stop velocity in a falling gameObject so it does not bounce. It only works about 80% of the time. Any ideas how to fix it or an alternative solution. I also use this code to trigger a 'Round' coroutine and I need it to be 100% reliable.

 void FixedUpdate () {
     var currentVelocity = GetComponent<Rigidbody>().velocity;
     
     if (currentVelocity.y <= 0f) 
     return;
     
     currentVelocity.y = 0f;
     
     GetComponent<Rigidbody>().velocity = currentVelocity;
     StartCoroutine(Round());
 }
