I have an Enterprise application hosted in HockeyApp.
The app is signed with Enterprise certificate and provisioning profile. I checked the expiration dates of both. Those are not expired.
When I am downloading the app in iOS 12, it crashes as soon as it opens. But works fine in lower iOS versions.
Here is the log i got through Xcode->Windows->Devices and Simulators:
Reason: Fence-hang-PROCESSNAME: 574ms handling fence, blown-fence (fence duration=575ms)
