Jisi Desktop for Mac crash on 2nd start

I just installed the jitsi desktop client for mac:
https://github.com/jitsi/jitsi/releases/download/Jitsi-2.10/jitsi-2.10.5550.dmg

downloaded from here:
https://desktop.jitsi.org/Main/Download

On first run i skipped the “assistant” and set the provision URL to my custom side (maybe i forgot to add the prefix “HTTPS://”). To let these setting to take effect i restarted the app. Now it is failing directly on startup - showing me a very long crash report.

Even uninstall (trashbin) + reinstall did not help.
Where to look for config files (if something is persisted)?
To not flood this forum with long crash reports: what is the correct github repo to file a bug report?

This is the legacy Jitsi Desktop client and has nothing to do with Jitsi Meet.
If you want to use jitsi-meet just use your browser. An electron desktop client for it is GitHub - jitsi/jitsi-meet-electron: Jitsi Meet desktop application powered by
