Windows Build started to crash

The game works in Editor, but crashes on splashscreen when built. Is was building fine before.

Okay, i found the reason for the crash.
Apparently, if you have serialized data in a singleton, you can not access it on declaration.

Having this:

Code (CSharp):

1. public static long GlobalRate = SomeSingleton.Instance.GlobalRate;
2. public static long GlobalHalfRate = GlobalRate / 2;

will crash your build and tell you absolutely nothing about reasons for the crash.
And because your Editor has this singleton initialized somehow, this will not crash the editor in runtime.
This should be caught before the crash somehow.
