      Getting a crash in release build

      > Attempting to JIT compile method '(wrapper delegate-invoke) TeamApp.Realm.TeamId <Module>:invoke_callvirt_TeamId_Team (TeamApp.Realm.Team)' while running in aot-only mode

      I got this once previously when using ReactiveUI's Fody weaver attributes, and was able to resolve by removing them. I started down the path of verifying if moving to SG would fix it here, but the current SG limitations make it hard to move over (e.g. #3085).

      Repro steps

      Similar to my issues with ReactiveUI, this came about pretty randomly after having done several release builds with Realm. The only thing I can think of that I added as an EmbeddedObject for the first time. Seemingly random, however.

      10.18.0

      Stacktrace of the exception/crash you're getting

      This is somewhat obfuscated by being the poorly symbolicated stacktrace in Crashlytics:
