My database has corrupted twice within 2 weeks… first on 31st Dec, and again today. It is running on Windows machine and I ensure I close Roon down fully before I turn my PC off. This issue, combined with Roon deciding to bomb out after it tries to redraw screen after a period of inactivity is making Roon 2.0 unusable.

@benjamin I will not restore my Roon database from backup in case you need to see it in its current state.
Hey @Framgeld,
We’re still attempting to connect to your core to enable diagnostics, if you could keep your core online that would be helpful!
An alternative option would be to have you upload manual core logs : use the directions found here and send over a set of logs to our File Uploader?
Did you load a fresh database, and experienced corruption? Or, did you restore a recent backup?
Hi @benjamin
I have opened Roon.
I restored a database after corruption on 31st Dec. I haven’t restored database this second time. I need to find a cause for the corruption before I restore again.
Hey @Framgeld,
We were able to take a closer look into your corruption, and found a corrupt album: Let’s Talk About Love by Céline Dion. This seems to be the source of your corruption from our investigation.
Please try removing this album from your watched folders, and let me know how things run

Many thanks. I will look into that.
@benjamin I don’t have that album in my library. There is very little Celine Dion, in fact (see images below) - I don’t like Celine Dion 
Not sure why Roon thinks this is in my library.
Anything else you can provide to help with this, e.g. is it a local folder, TIDAL, or Qobuz source?
Thanks.
I’m guessing it is related to this stack trace…?

Hey @Framgeld,
Odd indeed! As a next step, we’ll need to take a closer look at your database.
Here’s how you can send it over:
- Follow the recovery steps above
- Zip up your
RoonBackupsfolder (right-click it and select “Compress…”): - Submit the .zip file to us through our Database Corruption Issues portal
Thanks!
