I am getting following message when i try to run my code: Unhandled exception at 0x00007FFAAA12B450 (allegro-5.2.dll) in Game.exe: 0xC0000005: Access violation reading location 0x0000000000000030.

The part that gets the error (called Background.cpp):

#include "Background.h"
#include "Constants.h"
#include <allegro5/allegro_image.h>

Background::Background(std::string filename) { 
    backgroundImage = al_load_bitmap(filename.c_str());
    if (!backgroundImage) {
        std::cout << "Could not load the background image. Please check your path correctly: " << filename << std::endl;
    }
}

void Background::update() {

    x -= 2;
    if (x < - GAME_WIDTH) x = 0;

}

void Background::render() {

    al_draw_scaled_bitmap(backgroundImage, 0, 0, al_get_bitmap_width(backgroundImage), al_get_bitmap_height(backgroundImage), x, y, GAME_WIDTH, GAME_HEIGHT, NULL);

    al_draw_scaled_bitmap(backgroundImage, 0, 0, al_get_bitmap_width(backgroundImage), al_get_bitmap_height(backgroundImage), GAME_WIDTH + x, y, GAME_WIDTH, GAME_HEIGHT, NULL);

}

void Background::dispose() {
    al_destroy_bitmap(backgroundImage);
}

Constants.h contains the constants for GAME_WIDTH and GAME_HEIGHT.

Here is my Background.h:

#pragma once
#include <iostream>
#include <allegro5/allegro.h>

class Background{
  public:
    Background(std::string filename);
    void update();
    void render();
    void dispose();

  private:
    int x;
    int y;
    ALLEGRO_BITMAP* backgroundImage = NULL;
};

Just incase i am going to show my Game.cpp and Game.h:

#include "Game.h"
#include <allegro5/allegro_image.h>

Game::Game() {}

void Game::init() {
    background = new Background("res/stars.jpg");
}

void Game::update() {
    background->update();
}

void Game::handleInput() {}

void Game::render() {
    background->render();
}

void Game::dispose() {
    background->dispose();
}

#pragma once
#include "Background.h"

class Game {
  public:
    Game();
    void init();
    void update();
    void render();
    void handleInput();
    void dispose();

  private:
    Background *background;
};

My main.cpp:

#include <iostream>
#include <allegro5/allegro.h>
#include <allegro5/allegro_image.h>

#include "Constants.h"
#include "Game.h"

void update();
void render();
void handleInput();
void dispose();

Game game;

int main() {
    if (!al_init()) return -1;

    display = al_create_display(GAME_WIDTH, GAME_HEIGHT);
    event_queue = al_create_event_queue();
    timer = al_create_timer(1.0 / FPS); // fire 60x/s

    al_install_keyboard();
    al_init_image_addon();

    al_register_event_source(event_queue, al_get_display_event_source(display));
    al_register_event_source(event_queue, al_get_timer_event_source(timer));
    al_register_event_source(event_queue, al_get_keyboard_event_source());

    bool running = true;
    bool redraw = true;

    game.init();

    //game loop
    al_start_timer(timer);
    while (running) {
        ALLEGRO_EVENT event;
        al_wait_for_event(event_queue, &event);
        switch (event.type) {
        case ALLEGRO_EVENT_DISPLAY_CLOSE: 
            running = false; 
            break;
        case ALLEGRO_EVENT_TIMER:
            handleInput();
            update();
            redraw = true;
            break;
        }
        if (redraw && al_event_queue_is_empty(event_queue)) {
            redraw = false;
            render();
        }
    }

    dispose();


    return 0;
}

void update() {
    game.update();
}

void render() {

    //clear screen
    al_clear_to_color(al_map_rgb_f(0, 0, 0));

    //draw other game objects here
    game.render();

    // flip the page
    al_flip_display();
}

void handleInput() {
    game.handleInput();
}

void dispose() {
    game.dispose();

    al_destroy_display(display);
    al_destroy_timer(timer);
    al_destroy_event_queue(event_queue);
}

I hope you can help me with fixing this error XD.

I tried looking this error up but couldnt find annything
