Bootstrap switch not working properly when web page is resized

Question

This is the code:

<nav xmlns:sec="http://www.thymeleaf.org/extras/spring-security"  class="navbar navbar-expand-lg fixed-top container-fluid" id="navbar">
<div class="container px-4">
    <a class="navbar-brand" href="/main"> <img src="https://i.imgur.com/BKHVvT0.png" style="width: 100px; height: auto;"> </a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation"><span class="navbar-toggler-icon"></span></button>
    <div class="collapse navbar-collapse" id="navbarResponsive">
        <ul class="navbar-nav ms-auto">
            <li  sec:authorize="isAnonymous()" class="nav-item"><a class="nav-link" href="/login">Inicio sesión</a></li>
            <li  sec:authorize="isAnonymous()" class="nav-item"><a class="nav-link" href="/register">Registro Cliente</a></li>
            <li  sec:authorize="isAnonymous()" class="nav-item"><a class="nav-link" href="/registrohotel">Registro Hotel</a></li>

            <li sec:authorize="hasAuthority('CLIENTE')" class="nav-item"><a class="nav-link" href="/historialReservaClienteVigentes">Tus reservas</a></li>
            <li sec:authorize="hasAuthority('CLIENTE')" class="nav-item"><a class="nav-link" href="/perfilcliente">Perfil</a></li>
            <li sec:authorize="hasAuthority('CLIENTE')" class="nav-item"><a sec:authorize="isAuthenticated()" class="nav-link" th:href="@{/logout}"> <i class=" fas fa-door-open"></i></a></li>

            <li sec:authorize="hasAuthority('HOTEL')" class="nav-item"><a class="nav-link" href="/admin">Administrador</a></li>
            <li sec:authorize="hasAuthority('HOTEL')" class="nav-item"><a class="nav-link" href="/perfilhotel">Perfil</a></li>
            <li sec:authorize="hasAuthority('HOTEL')" class="nav-item"><a sec:authorize="isAuthenticated()" class="nav-link" th:href="@{/logout}"> <i class="   fas fa-door-open"></i></a></li>

        </ul>
    </div>
</div>

The fact is that it does appear on the screen, but when interacted with it does nothing. The switcher bottom does appear, but when clicked, it doesn't make the navigation items appear above it.

If you add bootstrap cdns: script and css, it will work. See the code snippet below:
