Thanks for writing in and sharing your report! In addition to what @Arlen has mentioned above - if you haven’t yet, I’d also safely stop Roon Server from running, and then power down your Mac.
Then, reboot and open Roon - let me know if you’re still running into the same issues after Roon has fully opened. Thank you!
The problem occurs when the record label replaces an album with a new version (such as remastered or hi-res), but your Qobuz favorite is still pointing to the old version which has been deleted. To fix it, follow my instructions here (you need to repeat for each affected album): https://community.roonlabs.com/t/unable-to-remove-corrupted-albums-from-roon-library-ref-was5hr/310115/7
It has happened to me many times and it is a big hassle to deal with.
