Theme JQuery inlcusion on WordPress 6.0 all the time fails

I’m writing right here as a result of i’ve WordPress 6.0, i’m attempting to incorporate JQuery in my theme beacuse i’ve to start out engaged on a performance i would like. The issue is that JQuery shouldn’t be loading accurately i suppose as a result of in my chrome developer console i received this error:

Jquery shouldn’t be acknowledged however i do not undersand why, as a result of i’ve all the time adopted WordPress practices and as you may see beneath within the code apparently there’s nothing unsuitable. WordPress has already its personal Jquery, i do not need an exterior Jquery library even in CDN, i do not skinny is required one other JQuery.

Right here is the code for enqueuing extra js scripts in features.php:

operate load_custom_jquery_edit(){
wp_enqueue_script('jquery');

wp_enqueue_script('customize-jq', 
                    get_template_directory_uri().'/belongings/js/customize-jq.js',
                    array('jquery'),
                    "1.1.0",
                    true);
}

add_action('wp_enqueue_scripts', 'load_custom_jquery_edit');

That is my JQuery extra file:

(operate($){
$(doc).prepared(operate(){
    //testing instance
    $('test-my-new-submit-btn')
    .attr('id','testBtn');

    $('#testBtn').on('click on', operate(e){
        e.preventDefault();
    
        let success_msg = "success!!!";
        
        alert(success_msg);
                    
        //Different issues to do subsequent
    });
});
})(JQuery);
