if (!file_exists($upload['basedir'].'/ulisting/css/'.$args['listing_type']->ID.'/'.$css_file_name.".css")) {

Solution 1:[1]

Try to verify what is actually in $args. Make some simple dump above your lines of code

    var_dump($args);die;
if (!file_exists($upload['basedir'].'/ulisting/css/'.$args['listing_type']->ID.'/'.$css_file_name.".css")) {
    $style_url = $upload['baseurl']."/ulisting/css/".$css_file_name.".css";
} else {
    $style_url = $upload['baseurl'].'/ulisting/css/'.$args['listing_type']->ID.'/'.$css_file_name.".css";
}

Not solved the full function is

public static function render($sections, $css_file_name, $args) {
    $content = "";
    $upload = wp_get_upload_dir();

    if (!file_exists($upload['basedir'].'/ulisting/css/'.$args['listing_type']->ID.'/'.$css_file_name.".css")) 
    {
        $style_url = $upload['baseurl']."/ulisting/css/".$css_file_name.".css";
    } else {
        $style_url = $upload['baseurl'].'/ulisting/css/'.$args['listing_type']->ID.'/'.$css_file_name.".css";
    }
    wp_enqueue_style('ulisting_builder_stytle_'.$css_file_name, $style_url);

    if(is_array($sections) AND !empty($sections)) {
        foreach ($sections as $section) {
            $content .= StmListingTemplate::load_template('builder/section',['section' => $section, 'args' => $args]);
        }
    }
    return $content;
}
