Masalah ini pernah dialami saat install Codeigniter 3 dengan XAMPP atau install Codeigniter 3 dengan Laragon dengan PHP versi 8.2

Merujuk dari referensi artikel berikut https://forum.codeigniter.com/printthread.php?tid=82678 ada dua cara untuk mengatasi problem di atas:

Menambahkan Variable Public

Tambahkan variable public di beberapa file yang muncul indikasi error seperti system/core/URI.php

File ./system/core/URI.php tambahkan variable public $config; di dalam Class URI

      /**
	 * Permitted URI chars
	 *
	 * PCRE character group allowed in URI segments
	 *
	 * @var	string
	 */
	protected $_permitted_uri_chars;

	/**
	 * CI Config
	 *
	 * @var	CI_Config
	 */
	public $config;
	
	/**
	 * Class constructor
	 *
	 * @return	void
	 */
	public function __construct()
	{
		$this->config =& load_class('Config', 'core');

di file ./system/core/Router.php   

class CI_Router {
  ...
  
  public $uri;

  ...

di file ./system/core/Loader.php 

class CI_Loader {

    public $load;
    public $benchmark;
    public $config;
    public $log;
    public $hooks;
    public $utf8;
    public $uri;
    public $router;
    public $exceptions;
    public $output;
    public $security;
    public $input;
    public $lang; 

di file ./system/core/Controller.php

class CI_Controller {

    public $benchmark;
    public $config;
    public $log;   
    public $hooks; 
    public $utf8;   
    public $uri;
    public $router;   
    public $exceptions;   
    public $output;   
    public $security;
    public $input;   
    public $lang; 
    public $db;     
    public $email;

Menambahkan Konfigurasi #[\AllowDynamicProperties]

Cara yang kedua adalah dengan cara implementasi atau menambahkan #[\AllowDynamicProperties] di setiap file yang muncul indikasi error sebelum definisi Class

defined('BASEPATH') OR exit('No direct script access allowed');
#[\AllowDynamicProperties]
/**

 */
class CI_URI {

Kalian tambahkan masing-masing di file URI.php, Router.php, Loader.php dan DB_Driver.php sebelum definisi Class

/system/core/URI.php

    #[\AllowDynamicProperties]

    class CI_URI {
   
   
/system/core/Router.php   

    #[\AllowDynamicProperties]

    class CI_Router {
   
   
/system/core/Loader.php 

    #[\AllowDynamicProperties]
   
    class CI_Loader {
   
   
/system/core/Controller.php     
   
    #[\AllowDynamicProperties]

    class CI_Controller {   
   
   
/system/core/DB_driver.php   

    #[\AllowDynamicProperties]

    abstract class CI_DB_driver {
