Roon Essentials crashes with iOS 11.2.1

I copied over my data from my iPhone 6 to a new iPhone X (iOS 11.2.1) and the app works, but every time I try to select ‘Library’ or ‘Services’ or ‘Support’, the app shuts down immediately. I’ve tried reinstalling the app. Same thing happens. I’ve updated my library and need to these functions to work. Any suggestions? thx!
