3Dprinting example throws Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED)

Hello,

I'm trying to use UWP to explore 3DPrinting Windows 10 API for repairing 3D models. In my application, I got an exception on the Printing3D3MFPackage.SaveAsync() call after loading a model and repairing it. I had some doubts about my application so I'd tried the UWP example called 3DPrinting and I get the same problem.

Here is the exception details : System.Exception HResult=0x8000FFFF Message=Défaillance irrémédiable (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED)) Source=Windows Arborescence des appels de procédure : à Windows.Graphics.Printing3D.Printing3D3MFPackage.SaveAsync() à SDKTemplate.Scenario1_Print.d__12.MoveNext() dans C:\Users\amau86\Documents\workspace\repair_tool\Windows-universal-samples-master\Windows-universal-samples-master\Samples\3DPrinting\cs\Scenario1_Print.xaml.cs :ligne 415

Is there any problem with my visual studio installation ? Tell me if you find a workaround. Byea
