I do not experience a full Windows lockup, just iTunes freezing completely so that I have to use Task Manager to kill the process and restart the app. My system and iTunes are fully updated. When the problem started, I was using only the built-in anti-virus/security. The bad behavior did not change after I installed Bitdefender. I have not tried to make a purchase since the problem started but I am an Apple Music subscriber and am frustrated that I have to restart the app regularly when I am listening.
I have, to date, not been keeping methodical notes, hoping that another update would come along and fix things. My informal impression is that the lockups are random-seeming, sometimes happening after a playlist ends, sometimes when I switch from search results to a playlist in my library, sometimes when I switch between an Apple playlist and one of my own.
I am a public servant and cannot afford Apple hardware, so I cannot try that 'workaround.' I very much hope that the coders will be permitted to address this problem soon. Also, I'm not very familiar with the Apple website--if anyone knows a better place to report a problem like this, please type up.
