I’m using Godot 3.0 Beta1-Mono installed on Windows 10 machine

When I’m trying to play game build ends correctly, the game starts, but almost immediately freezes and chrash. In command line i have:

This problem appears when I’m using C# scripts. But when I delete any C#-like existance and use only GDScript it runs without any problems
