iTunes not opening after Apple Music trial

I just started my Apple Music trial on my MacBook Pro (El Capitan). However, now when I open it, it opens and immediately closes afterwards. The only way I can make it stay open is in safe mode, in which my apple music playlists aren't saved. How can I open it properly?

I have tried restarting my laptop, uninstalling, reinstalling, and updating iTunes and none have worked so far. Please help
