Why do sprites disappear if I change the color with a script?

Question

Unity

Here I have a circle consisting of 24 fragments, I painted 1 fragment with my hands, everything is fine, there is a color There


is a script on the fragment like this

using UnityEngine;

[RequireComponent(typeof(SpriteRenderer))]
public class Fragment : MonoBehaviour
{
    public FragmentColor ElementColor;
    private Circle _circle;
    private SpriteRenderer _sprite;
    private void Awake()
    {
        Circle circle = GetComponentInParent<Circle>();
        if (circle == null)
        {
            Debug.LogError("Fragment parent must have a Circle script");
        }
        else
        {
            _circle = circle;
        }
        _sprite = GetComponent<SpriteRenderer>();
    }

    private void Start()
    {
        Color color = _circle.GetColor(ElementColor);
        _sprite.color = color;
    }
}

After I start the games, the fragment with the script just disappears, but the color changes correctly, the object itself is in the same place and the sprite has not changed

You have transparency at zero, so you can't see anything. As always , no one provides
the necessary code , because they think that the error is probably in the banal assignment of values._circle.GetColor(ElementColor)
