问题
My application is signed with Enterprise distribution certificate. When I try to install my app on iPhone X it installs successfully but when I try to open, it gives me an error "This app was not installed from the App Store and must be reinstalled manually"
Please note that app is opening and working on all other devices. This issue occurs only some specific iPhone X, not on every iPhone X.
Can someone please tell me why I am facing this error.
Screenshot is attached

The app may have been offloaded. Offloading is a new iOS 11 feature that allows user or the iOS system to remove an app to free up space without deleting any of its configurations or settings.
To know if an app has been offloaded, it displays a small cloud icon in front of its name.
When opening an offloaded app, Apple tries to download the app back from App Store. Since it's an enterprise app that's not available on App Store, it can't download it and shows up this error.
The solution? Well, just what Apple says: "This app was not installed from the App Store and must be reinstalled manually". Download the enterprise app again from where it's hosted and install it.
