Exception thrown System.TypeInitializationException at WinRTBridge on Windows phone device

Unity Engine

Hi

I’m recently upgrading to Unity 5.3.8f1 and recently I got the issue of the app crash during the startup on Windows phone device.

Code

_bridge = new WinRTBridge.WinRTBridge();
appCallbacks.SetBridge(_bridge); <----- Exception at this.

Here is the error log I got from Visual Studio:

Exception thrown: ‘System.TypeInitializationException’ in FVCE.exe

I found the (sort-of) similar thread System.TypeInitializationException at appCallbacks.SetBridge(_bridge) - Unity Engine - Unity Discussions. However it doesn’t actually pinpoint the exact cause and it looked like the issue was resolved with 5.3.5p2, but I’m already on 5.3.8f1. Isn’t the fix being ported over?

That doesn’t look like a crash. What happens when you just hit continue in the break popup dialog?

If I hit continue in the breakpoint then I’d get the break popup dialog in Visual Studio and the game will crash.

In short, after I’ve debugged a little bit more, it turns out there are InnerExceptions related to ‘cannot reduce access’ under System.InitializationException and it is related to abstract method defined as ‘protected’.

I’m still perplexed why it becomes the issue in Unity 5.3.8f1. The previous version of Unity I used 5.3.1p3 has no issue with it.

I’ve also filed the ticket with Unity.

Is the method it is complaining about located in a nested class by any chance?
