TooltipService crashes with NullReferenceException and no further exception information (Exception Code 80004003) when binding to property returning null
I'm delevoping an app and I have some serious Problems with an NullReferenceException I can't handle.
When using the debbuger the app crashes here (screenshot) with an NullReferenceException and no further information. I also configured my Visual Studio to stop every time a NullReferenceException is thrown, but it doesn't stop anywhere.
I stared the app in the release-mode and uploded the WER Report file here: Report.wer
It shows an exception code of 80004003 which I identifed as INVALID_POINTER exception, but I'm not able to figure out where the problem ist.

You might consider opening a support case for assistance with this:
If you're skilled at WinDbg debugging, you could attach either DebugDiag or WinDbg to capture either a dump or do a live debug.

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.
