Description Of Issue
Selected fewer than 10 albums for re-scan under Album Edit panel. Re-scan stuck with no progress after more than 12 hours. Never-ending spinner. No obvious way to stop/restart re-scan. Previously worked fine.

Just restart the Mac if you have not already.

Tried that 3-4 times already. But the stuck re-scan is still there after restarting.

OK, the next step is to figure out if a corrupt file is tripping it up. Move the files and see if it normalises. If it does add them one by one until you find the one causing the issue.

I did move 6 albums out of my library. That reduced the stuck re-scanning from 1/4 to 1/2 albums. But don’t know now which two albums are still stuck. I’ve re-scaned dozens of albums (successfully) over the past few days, and I’m not aware of how to see which two albums are causing the remaining problem.

After nearly 24 hr of the hung re-scan, the Roon desktop app crashed. After relaunch the stuck re-scan problem was gone (!). I restored the previously moved music files back to my library and Roon promptly re-imported them and automatically re-scanned them without complaint. Go figure.
