My Question or Issue
As the subject says, when I open another app, I get Content Unavailable and all songs grey out, but song keeps playing.
If I restart my PC and open the desktop app, I can play songs normally. While it's playing, if I open other apps (I have not done a long test with a bunch of apps, but I know Adobe XD is one), then the songs are immediately greyed out. The music continues to play, and will even play the next song on the playlist when a song ends, but if I try to choose any song I will get the "Content Unavailable" alert and sometimes the alert saying that the session is offline (it's not). The only way to get it working again is to restart the PC, and that doesn't work 100% of the time.
I have tried clean installs several times with no change.
