Can't play Apple Music from one Itunes PC - OK everywhere else

For a couple of months now I have not been able to play Apple Music from my work PC. I have called support a couple of times, one time they had me uninstall and reinstall, which didn't work. Another time he told me that since I had a different AppleID for music than iCloud that was the problem and I had to change my AppleID. Not going to do that.

I've seen all the suggestions about signing out and back in, showing in Apple Music, deleting SubscriptionPlayCache, etc. and nothing seems to work. My home PC works fine and it's on the same version. This is very frustrating. I use the work PC all day and like to listen to my music and I am missing a good portion of it since I have been on Apple Music for a few years now.
