I seem to be encountering a rare issue. Every time I launch the Music app, it crashes immediately. I found one post (with no replies) in the Apple Developer Forums that describes the same behavior. Other than that, there seems to be no documented troubleshooting attempts for this problem.
Here's the header data of the crash report in case that helps.
