Exception in UWP on device and emulator

So, the problem: I have working application on UWP, written on C# and C++. It works as it must work on desktop in releas and debug modes. It worked on mobile devices and emulator not so long before some changes happend in C++ part. But now application crashes at the begining of C++ part if application opens on emulator or mobile. MSVS gives me this messages, but It does't helped:

• Exception thrown at 0x7767B928 (ntdll.dll) in rhodes.exe: 0xC0000139: Entry Point Not Found.
• Exception thrown: 'System.Runtime.InteropServices.COMException' in System.Private.Interop.dll
• The specified procedure could not be found. (Exception from HRESULT: 0x8007007F)
• Exception thrown: 'System.Runtime.InteropServices.COMException' in System.Private.Interop.dll
• Exception thrown at 0x76EA2812 (KernelBase.dll) in rhodes.exe: 0x40080201: WinRT originate error (parameters: 0x8007007F, 0x00000050, 0x03B0E2DC).

Any ideas?

Go to Debug -> Windows -> Exception, and enable breaking on all exception types (C++, CLR and Win32) ones. Depending on where the issue comes from, you'll need to use either native or managed mode debugging (you can set it in Project Properties -> Debug tab). Now, the project should hit a breakpoint when you hit that exception, which will point you to where it is coming from.
