a few days after we publish and archive application, new users who had just downloaded and installed application, can't open.

after every new realease, our users could able to download, install, use our application without any problem. But a few days later, new users who had just downloaded and installed application, can't open. One second a black screens seems then app crashed. At this time, the user who download a few days ago could able to use everything. We have checked the logs and there is something like "System Policy: MAP_JIT requires the dynamic-codesigning entitlement" and "Got a SIGABRT while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application.". By the way our app is developed via Xamarin Forms.
