Visual Studio 2017 Design XAML bug, does not recognize Resources

Question

internal static System.Drawing.Bitmap radio_hover_btn {
    get {
        object obj = ResourceManager.GetObject("radio_hover_btn", 
resourceCulture);
        return ((System.Drawing.Bitmap)(obj));
    }
}

I’m having trouble with this code above, it just doesn’t find my png radio_hover_btn and alleges error during execution:

System.resources.Missingmanifestresourceexception System.resources.Missingmanifestresourceexception occurred Hresult=0x80131532 Message=No suitable resource for the specified crop (or neutral crop) was found in the given Assembly. Check whether "truckersmplauncher.properties.Resources.Resources" has been incorporated or linked to Assembly "Truckersmplauncher" correctly at compile time or whether all required satellite assemblies can be loaded and are fully signed.

The "buttons" that are actually images turn transparent color, but still perform the click function.
