MenuItem cannot be popuop and the clieck not work for the menu item in asp.net

Question

I have updated from 2016 to 2020. However, when I try to hover on a menu that will pop up menu item. It always cannot prompt.

Here is the code

$(document).ready(function () {
    $(document).on("mouseenter", ".customMenuItem", function () {
        var menuItem = $(this);
        // Remove rmItem class
        menuItem.removeClass("rmItem");
        openMenu(menuItem);
    });

    $(document).on("mouseleave", ".customMenuItem", function () {
        var menuItem = $(this);
        // Remove rmItem class
        menuItem.removeClass("rmItem");
        closeMenu(menuItem);
    });

    $(window).resize(function () {
        adjustMenuTileContainer();
    });

    adjustMenuTileContainer();        

    $("#wrapperContent").click(function () {
        $(".openc").each(function () {
            $(this).removeClass("openc");
        });
    });

    //$(".menuTile").click(function () {
    //    window.location.href = $(this).attr("navigateurl");
    //});

    $(document).on("click", ".menuTile", function () {
        window.location.href = $(this).attr("navigateurl");
    });       
    
});

And for the openMenu(menuItem), for 2016 version, the menuItem will always be li.customMenuItem. However in 2020, it will becomes "li.rmItem.customerMenuItem", thus the css is not work. So how can I fix this issue?

And when the menuItem is popup, the menu cannot be clicked. seems the asp:panel is not properly rendered.

                        </Items>
                    </telerik:RadMenu>

When I click the menu item, it won't go into the click function.

$(document).on("click", ".menuTile", function () {
        window.location.href = $(this).attr("navigateurl");
    });

seems the click is not work in for the menu item, what is the possible reason and how I can debug and fix it?
