Same problem…blocked on this message.
Started on my Win 10 PC.
Uninstall / Reinstallation worked only one time.

Now I tried to reinstall it on my MAC.
Same issue, never worked.

I tried to remove my librairies from my NAS, tried to remove my Qobuz account, changed the settings of my Streamer, nothing worked.
Very annoying to say the least…

Any real solution ?
I see a lot of that complaint / issue…
