Unity 2018.1 hard crashing on Android when instantiating an object with a certain component

Hello

I am upgrading my project from Unity 5.6 to 2018.1. So far, everything seems to work besides some minor issues here and there, mostly from outdated 3rd part assets. The one issue I am battling with is a hard game crash on Android.

The adb logcat does not give any meaningful information besides the fact that the game process died. Here's how the log looks like after last Unity debug log triggered by my code:

Because the above log turned out not to be very helpful, I started trying to isolate the issue in my scene. I narrowed it down to a single component on a prefab spawned at runtime. If I remove the component from the prefab, the game does not crash.

Now here's the crazy part: the aforementioned component is a very basic component that doesn't actually do much. Here's the full code for the component: https://hastebin.com/emakolopej.cs
The code in Awake isn't even executed as indicated by adb log - the crash happens before Unity invokes the Awake method on it. Moreover, it does not matter if the GameObject that has the component attached is enabled or not - simply instantiating it is enough to crash the game.

Additionally, I am using the same prefab, with the same components, in other parts of the scene but they are preinstantiated - they are part of the scene at scene load and are not instantiated at runtime. These do not cause any issues.

The prefab in question is a UI widget, so a GameObject with a RectTransform; always a child of some Canvas.

Any ideas how to troubleshoot this further? Or maybe somebody is aware of a known bug?

 

I think there are some missing parts in this crash. can you post a full log, from the time the app / game is started until the crash (5 seconds after the crash would be better).

 

@Aurimas-Cernius The issue went away after updating to Unity 2018.1.2. Probably thanks to this: https://issuetracker.unity3d.com/is...null-value-with-performance-reporting-enabled

Although, the cause of the crash was different. I pinpointed it to spawning a BaseBehavior (from FullInspector) object at runtime. Even an empty BaseBehaviour component, with no logic in itself was enough to reliably crash the game. I tried creating a repro project but in a fresh project it doesn't crash. Probably something to do with different player settings, services and Android manifest? Anyway, the issue seems to be resolved. Thanks.
