What is actually happening?

Getting errors and warnings.
In the terminal:

Module '"../../node_modules/vue-router/dist/vue-router"' has no exported member 'RouteConfig'.
  > 1 | import { RouteConfig, createRouter, createWebHistory } from 'vue-router'
      |          ^
    2 | import Home from '../views/Home.vue'
    3 | 
    4 | const routes: Array<RouteConfig> = [

In the browsers console:

Uncaught TypeError: Super expression must either be null or a function

The codesandbox.io does not accurately reproduce the error, not sure why, because I uploaded my GitHub repo to it.

The CLI plugin for vue-next is still WIP: vuejs/vue-cli#5637. Since you are also using Vue-property-decorator, you will also need to make sure to use the correct versions: kaorun343/vue-property-decorator#294

Some types like RouteConfig have been renamed, so please refer to each project documentation or README to find those (e.g. https://github.com/vuejs/vue-router-next#typings).

There is quite a lot to this but it's not a bug on Vue. I recommend you to use the Discord server to ask questions.

Makes sense, thanks for the reply.
I will use the discord server for future questions.
