Windows update corrupts struct construction in .Net 4.x

Since the installed of a Windows update on 14.9.2017 we have problems creating certain structs in our release builds. I have noticed that compiled code on computers without that update runs as expected ("Wrong start: 1.1.1990..."), on computer with the update in question installed, the code is not working correctly ("Wrong start: 1.1.2000..."). This happens in all versions of the .NET Frameworks starting from version 4.x.

 class Program
    {
        static void Main(string[] args)
        {
            DateTime start1 = new DateTime(1990, 1, 1, 6, 0, 0);
            DateTime end1 = new DateTime(2000, 1, 1, 6, 0, 0);
            var r2 = new DateTimeRange(start1, end1);
            var r3 = new Range<DateTime>(r2.From, r2.To);
            Console.WriteLine($"Wrong start: {r3.From}, correct start: {start1}");
            Console.ReadLine();
        }
    }

   public struct DateTimeRange 
    {
        private Range<DateTime> m_range;

        public DateTimeRange(DateTime from, DateTime to)
        {
            m_range = new Range<DateTime>(from, to);
        }


        public DateTime From
        {
            get { return m_range.From; }
        }

        public DateTime To
        {
            get { return m_range.To; }
        }
    }

    public struct Range<T> where T : struct
    {
        private T m_from;
        private T m_to;


        public Range(T from, T to)
        {
            m_from = from;
            m_to = to;
        }


        public T From
        {
            get { return m_from; }
        }

        public T To
        {
            get { return m_to; }
        }
    }
