Also, again, on Windows 11; the quick fix for my copy getting stuck on analyzing seems to be launching the Amazon Music desktop app, being logged in, and leaving it running in system tray. This was only way I could get my downloads to restart today. There is also a component that can launch at startup, but I disabled that yesterday just to see if any impact today. If you can imagine "tunneling" the desktop app "seems" to bless the IP connection, then starting MusicFab will get things going again. This worked, whether anecdotal or coincidental, but this also got me restarted 2 days ago (I am downloading HD versions of all the CDs I already own, but in 24/96 where available, so it's a *lot" pending in my queue.
Just a thought to those who run into the stall out issue. Worth a try :)
