The problem of gallery access and gallery opening not working in Android 13 (Kotlin)

Why doesn't the gallery open when I click the button even when I throw a toast in the setonclicklisener code? What is the problem?
I have also placed an imageview so that when a photo is selected from the gallery, it will be placed in the imageview section, but I cannot access the gallery at all.

main_activity.kt:

package com.example.test

import android.Manifest
import android.content.Intent
import android.content.pm.PackageManager
import android.os.Bundle
import android.provider.MediaStore
import android.widget.Button
import android.widget.ImageView
import android.widget.Toast
import androidx.activity.result.contract.ActivityResultContracts
import androidx.appcompat.app.AppCompatActivity

class MainActivity : AppCompatActivity() {
    lateinit var btn: Button
    lateinit var imageView:ImageView
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        init()
    }
    fun init(){
        bindView()
        btn.setOnClickListener { checkAndOpenGallery() }
    }
    fun bindView(){
        btn = findViewById(R.id.btn)
        imageView = findViewById(R.id.imageView)
    }

    fun checkAndOpenGallery() {
        if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
            == PackageManager.PERMISSION_GRANTED
        ) {
            openGallery()
        } else {
            requestGalleryPermission.launch(Manifest.permission.READ_EXTERNAL_STORAGE)
        }
    }

    fun openGallery() {
        val intent = Intent(Intent.ACTION_PICK, MediaStore.Images.Media.INTERNAL_CONTENT_URI)
        requestImageLoad.launch(intent)
    }


    private val requestGalleryPermission = registerForActivityResult(
        ActivityResultContracts.RequestPermission()
    ) { isGranted: Boolean ->
        if (isGranted) {
            openGallery()
        } else {
            Toast.makeText(this, "permission de deind", Toast.LENGTH_SHORT)
        }
    }

    private val requestImageLoad =
        registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->
            if (result.resultCode == RESULT_OK && result.data != null) {
                val img = result.data?.data
                imageView.setImageURI(img)
            }
        }
}

activity_main.xml:

       <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="212dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        tools:ignore="ContentDescription,ImageContrastCheck"
        tools:srcCompat="@tools:sample/avatars" />

    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="196dp"
        android:text="@string/open_gallery"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent" />

android manifest:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

I wanted the gallery to open when I click the button but nothing

(Behaviour changes: Apps targeting Android 13 or higher)

You should use the new Photo picker which was introduced with Android 13 SDK (API 33).
