6.4.0

Description

When trying to translate the url using the router prefix feature the following error occurs:
Target route "app_your_route_name" for alias "App\Controller\YourController::index" does not exist.

How to reproduce

• Create a fresh installation of 6.4.0 (or upgrade a fresh installation from 6.3 to 6.4).
• Create a dummy controller (e.g. with the maker bundle)
• Change routes.yaml (https://symfony.com/doc/current/routing.html#localized-routes-i18n):

controllers:
    resource:
        path: ../src/Controller/
        namespace: App\Controller
    type: attribute
+   prefix:
+       de: '/de'
+       fr: '/fr'
+       it: '/it'

• run bin/console cache:clear
