Android IL2CPP Weak References error

[batonPiotr]

Hello!

I have following issue: I bind a very simple view with one button:

dataContext = new MainMenuViewModel(commandDelay);
this.SetDataContext(dataContext);

/* databinding */
BindingSet<MainMenuViewController, MainMenuViewModel> bindingSet = this.CreateBindingSet<MainMenuViewController, MainMenuViewModel>();
bindingSet.Bind(this.runButton).For(v => v.onClick).To(vm => vm.OnRun).OneWay();

bindingSet.Build();

OnRun in this case is a simple public void method in the MainMenuViewModel. It works just fine in the editor but when I compile it to android I get following error:

It must have been because of the newest update. I've used this case before without problems in older versions but I cannot recall which one was it.
