Various transform in coroutine

[quartz river]

Sorry if it's a dumb question but I'm just having fun with personal projects and I ran into these issue

When I press space I execute StartCoroutine(SuperAction())

This is the code:

private IEnumerator SuperAction()
    {
        //flag for movement
        _isMoving = true;
        _isGrounded = false;
        //wait untill he completly stops
        yield return new WaitUntil(() => rb.velocity == Vector3.zero && rb.angularVelocity == Vector3.zero);
        //propelled to the air
        rb.useGravity = true;
        rb.AddForce(jump * jumpForce, ForceMode.Impulse);
        //stop at predetermined height
        yield return new WaitUntil(() => rb.transform.position.y > 5.0f);
        rb.velocity = Vector3.zero;
        rb.angularVelocity = Vector3.zero;
        rb.useGravity = false;
        //Does stuff in air
        var startTime = Time.time;
        while ((Time.time - startTime) < 2)
        {
            rb.transform.Rotate(new Vector3(Random.Range(0, 1f), Random.Range(0, 1f), Random.Range(0, 1f)) * rotatingSpeed);
            yield return new WaitForEndOfFrame();
        }
        //Set himself to direction ###Seems to stop here and idk why###
        var rotationVector = RollToSetFace();
        while (rb.transform.eulerAngles != rotationVector)
        {
            rb.transform.eulerAngles = rotationVector * Time.deltaTime * rotatingSpeed;
        }
        //To be added: Dice lands facing the correct direction
        _isMoving = false ;
        _isGrounded = true;
    }
}

private Vector3 RollToSetFace() {
        var quaternionVector = new Vector3();
        switch (1)
        {
            case 1:
                quaternionVector.x = 90;
                break;
            case 2:
                break;
            case 3:
                quaternionVector.y = -90;
                break;
            case 4:
                quaternionVector.y = 180;
                break;
            case 5:
                quaternionVector.y = 90;
                break;
            case 6:
                quaternionVector.x = -90;
                break;
            default:
                break;
        }
        return quaternionVector;
    }

What is the issue you are running into

[quartz river]

The dice spins then it doesn't go past the second while

Sorry it wasn't that clear I marked it with ###

//Set himself to direction ###Seems to stop here and idk why###
        var rotationVector = RollToSetFace();
        while (rb.transform.eulerAngles != rotationVector)
        {
            rb.transform.eulerAngles = rotationVector * Time.deltaTime * rotatingSpeed;
        }

stops here
