The character moves, but does not turn in the direction of movement. How to fix it?

Question

C++ / C#

The character moves and there is an animation of movement, jumping and standing still, but he does not turn in the direction of movement and looks at one point. Please help me fix this.
Here is the code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Player : MonoBehaviour
{
    public float speed;
    public float jumpForce;
    private float moveInpute;

    private Rigidbody2D rb;

    private bool facingRight = true;

    private bool isGrounded;
    public Transform feetpos;
    public float checkRadius;
    public LayerMask whatIsGround;

    private Animator anim;

    private void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        anim = GetComponent<Animator>();
    }
    private void FixedUpdate()
    {
        moveInpute = Input.GetAxis("Horizontal");
        rb.velocity = new Vector2(moveInpute * speed, rb.velocity.y);
        if (facingRight == false && moveInpute > 0)
        {
            Flip();
        }
        else if (facingRight == true && moveInpute < 0)
        {
            Flip();
        }
        if (moveInpute == 0)
        {
            anim.SetBool("isRunning", false);
        }
        else
        {
            anim.SetBool("isRunning", true);
        }
    }
    private void Update()
    {
        isGrounded = Physics2D.OverlapCircle(feetpos.position, checkRadius, whatIsGround);

        if (isGrounded == true && Input.GetKeyDown(KeyCode.Space))
        {
            rb.velocity = Vector2.up * jumpForce;
            anim.SetTrigger("takeOF");
        }
        if (isGrounded == true)
        {
            anim.SetBool("isJumping", false);
        }
        else
        {
            anim.SetBool("isJumping", true);
        }
    }
    void Flip()
    {
        facingRight = !facingRight; 
        Vector3 Scaler = transform.localScale;
        Scaler.x *= -1;
        transform.localScale = Scaler;
       
    }
     
}

Answer 1

transform.rotation = Quaternion.LookRotation(rb.velocity);
