App called Musictube wont delete off of icloud

I’ve had this app that’s been stuck on my icloud for years. I can’t reinstall the app to try to delete it again because the app itself no longer exists. I’ve tried also factory resetting the app but it doesn’t work. I’ve even tried simply pressing the ‘delete data’ option but all it does is crash. I’m not sure what to do and nobody has been able to help me.
