Steps to reproduce the issue

Create new menu items. In this case I created three different types:

1. Single article (alias 'test')
2. Category blog (alias 'category-blog')
3. Login (alias 'login-form')
   All on the main menu with standard Public access and all published.

Expected result

To reach any of these pages when clicking the link in the main menu

Actual result

1. The menu items are displayed on the main menu
2. The URL is displayed at the bottom left of the browser (Firefox) as normal, when hovering over the main menu item link
3. Clicking on the link results in a 404 error:

System information (as much as possible)

Using Joomla! 4.0.0-alpha7-dev (from a few days ago) on CloudAccess.net website
Different browsers have the same result
