Hey @Jeff_S,
Thanks for the update! It does appear that this may be a local library issue, if the start-up performance feels good when your local library isnât added to your database.
You can certainly restore from a backup, or re-add your watched folders. You will probably revert back to the ~8 minute start up time when doing this.
When looking into your account, I see you have a Synology NAS that is currently running Roon Server. Did you recently swap cores in testing?
When reviewing your Nucleus diagnostics, I did see a handful of corrupt files. They appear to be:

However, I wouldnât expect 9 or so tracks to affect performance. If you can, I would re-transcode the above tracks to .flac and see if that may help. What do you use to edit metadata?
