Clicking custom plugin admin menu redirects to “No Update Required” on live site

The bug was caused because of sloppy code design. Which lead to using too many require.

Changing

function plugin_setup_menu()
{
        $icon_url = PLUGIN_URL . "public/images/dash-icon.png";
        add_menu_page(__(PLUGIN_NAME, PLUGIN_SLUG), __(PLUGIN_NAME, PLUGIN_SLUG), 'manage_options', PLUGIN_SLUG, array('views', 'admin'), $icon_url);
}

to

function plugin_setup_menu()
{
        $icon_url = PLUGIN_URL . "public/images/dash-icon.png";
        add_menu_page(PLUGIN_NAME, PLUGIN_NAME, 'manage_options', PLUGIN_SLUG, array($this,'admin_menu_view'), $icon_url);
 }

and adding another method

function admin_menu_view()
{
    include_once PLUGIN_PATH . 'views/admin.php';
}

fixed the issue for me.
