The message "Error: Unknown custom element: <router-view> - have you properly registered the component?" is prompting for a solution

Even though the name is correctly capitalized in all my component instances, I am still encountering an error. After researching similar issues online, it appears that the problem usually revolves around naming discrepancies. However, I have double-checked and confirmed that all my components have identical names to those listed in the routes.js folder. Any suggestions for potential solutions would be greatly appreciated. Thank you.

When working in your main file, make sure to include the following:

new Vue({
    el: '#app',
    router: VueRouter,
    render: h => h(App),
