Can't run your repo right now but: have you tried it with an updated verion of @vue/sfc-compiler as well? Your current lockfile still refers to alpha-1:

"@vue/compiler-sfc@^3.0.0-alpha.1":
  version "3.0.0-alpha.1"

Just like vue-template-compiler in Vue 2, this dependency has to be kept in sync with the Vue version that's being used.

It seems that vue-next is updated, but @vue/compiler-sfc is not!

@vue/compiler-sfc verson is 3.0.0-alpha.1

You need to adapt the mounting code:

-const app = createApp()
+const app = createApp(App)
-app.mount(App, '#app')
+app.mount('#app')

This was one of the breaking changes: https://github.com/vuejs/vue-next/compare/v3.0.0-alpha.3...v3.0.0-alpha.4
