Supervisor Error when trying to update HomeAssistant

Yesterday I installed HomeAssistant Supervised on a freshly installed Debian 11.7.0 system. When I try to join the Beta I get the error to check the Supervisor log. In there, there are two errors about the supervisor, which both correspond to the time I tried to join the beta.

/supervisor/reload return code 500

Is anybody able to help me?

I solved it by redoing the installation. Works fine.
