Stopped working? – ICD10 Consult Review

I have an iPhone 6plus, the app suddenly stopped working, please help! When I go to open the app, the app starts up then immediately closes. I have plenty of space on my phone, just recently updated to the most resent iOS, even tried downloading and reinstalling the app. I loved this app and have been using it for years. Will change to 5 star review if I can get this fixed.
