iTunes hangs on start
I am currently unable to open iTunes 12.8 on my Mac. If I launch the application, the iTunes icon appears in the dock as if the application is open, but no application window appears. If I then go to Force Quit Applications, it shows "iTunes (not responding)".
I have tried a Safe Mode boot, but that didn't solve the problem.
Any ideas? Thanks
iMac, macOS High Sierra (10.13.6)
