I rolled back to v0.5.0-rc.8.1 and it works. And it's impossible to fix this issue without rolling back a version, because the appservice management requires the server to be up and running.

The appservices I have running are mautrix/meta and mautrix/whatsapp bridges.

I just decided to upgrade my server after the newest release, and upon downloading the new Docker image and restarting my container, I can no longer use Conduit, due to a fatal error with appservice registration: ```bash 2025-12-25T22:36:53.670708Z WARN conduwuit_core::config::check: No support contact information (support_email or support_mxid) is configured in the well_known section.

Upon further investigation I found out I had two unused services:

Appservices (4): , meta, telegram, whatsapp

I could unregister telegram successfully as I'm not using it, but the first appservice has an empty name and I have no idea how to unregister it, as the commands fail assuming there is an empty parameter passed to the commands.
