I need help with this error i have been having error CS0131: The left-hand side of an assignment must be a variable, property or indexer(line: 59)i’ve searched on google couldn’t find an answer. What am i doing wrong?

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

public class PlayerMovement : MonoBehaviour
{
     public float speed;
     public float jumpForce;
     private float moveInput;
  
    private Rigidbody2D rb;

    private bool facingRight = true;

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

    private int extraJumps;
    public int extraJumpsValue = 1;

    // Start is called before the first frame update
    void Start()
    {
        extraJumps = extraJumpsValue;
        rb = GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void FixedUpdate()
    {
        isGrounded = Physics2D.OverlapCircle(groundCheck.position, checkRadius, whatIsGround);



        moveInput = Input.GetAxisRaw("Horizontal");
        Debug.Log(moveInput);
        rb.velocity = new Vector2(moveInput * speed, rb.velocity.y);

        if(facingRight == false && moveInput > 0 ){
          Flip();

        }else if(facingRight == true && moveInput < 0){
            Flip();
        }

    }
    void Update(){
      
        if(isGrounded == true){
            extraJumps = extraJumpsValue;
        }

        if(Input.GetKeyDown(KeyCode.Space) && extraJumps > 0){
        extraJumps--;
        rb.velocity = Vector2.up * jumpForce;
        }
        else if(Input.GetKeyDown(KeyCode.Space) && extraJumps == 0 && isGrounded = true){
         rb.velocity = Vector2.up * jumpForce;
        }
    }

    void Flip(){

        facingRight = !facingRight;
        Vector3 Scaler = transform.localScale;
        Scaler.x *= -1;
        transform.localScale = Scaler;
    }
}

Pretty sure you meant == true instead of = true in line 59. Also, isGrounded == true is the same as just isGrounded. And isGrounded == false is the same as !isGrounded. There is no need to compare a bool to a (hardcoded) bool.
So you may as well just write && isGrounded there
