System.NullReferenceException occurred in ffme.win.dll

Getting System.NullReferenceException during form initialization

During initializecomponent the IDE is throwing a nullreferenceexception from ffme.win.dll. The stacktrace shows some partial information with "at Unosquare.FFME.Platform.GUIContext..ctor() I have built a control using VB.NET and the control works in a much smaller test project just fine, but when I include the same control and call it the same way in a larger project I am getting the above error. I have wrapped InitializeComponent inside a try-catch, but it never falls into the catch while in the IDE. I can disable breaking for this error and things work correctly, but it seems dangerous do disable breaking for a nullreferenceexception as it disables it globally. Oddly the compiled code runs fine so it has to be some environment setting that is outside of my knowledge...
