Error while adding page template from custom plugin wordpress

Question

add_filter( 'theme_page_templates', 'sf_add_page_template_to_dropdown' );

function sf_add_page_template_to_dropdown( $templates ){
   $templates[PLUGIN_URL.'templates/quiz-template.php'] = __( 'Page Template From Plugin', 'text-domain' );

   return $templates;
}




add_filter( 'template_include', 'pt_change_page_template', 99 );

function pt_change_page_template($template){
    if (is_page()) {
        $meta = get_post_meta(get_the_ID());
     
        $template = $meta['_wp_page_template'][0];

    }

    return $template;
}

I'm using this code in plugin file to add a custom page template from my plugin. Template is showing in ( Page Attributes -> Template ) but the error coming on frontend is ->
