I manage to create a local test environment.
I removed every extension which has no beta 15 version.

Base URL: http://10.0.1.8
Installation path: /flarum
Debug mode: off
After this I simply get a HTTP ERROR 500 from the main page.
In the logging the following error occurs
[2021-01-10 15:52:01] flarum.ERROR: Symfony\Component\Console\Exception\NamespaceNotFoundException: There are no commands defined in the "schedule" namespace. in /flarum/vendor/symfony/console/Application.php:604
Stack trace:

Any ideas to help me out? I like to upgrade our production envirnoment but this is kind of a showstopper...
