VS 2019 crashes when using WPF

When i open my WPF-Project in Visual Studio 2019 i can write my code just as normal but when i open the *.xaml-File to edit my window it crashes and restarts.

I experience the same issue when I open WPF-Project in Visual Studio 2019. I hope an update to fix the issue is released soon. This is a nice extension to Visual Studio 2019.
