In a mixed UWP c++/c# project, enabling "Complie with .NET Native tool chain" results in blank screen without useful debug information

I'm having troubles with my react-native-windows app submission to the microsoft store due to app certification prbolems. As described in this issue: microsoft/react-native-windows#4516 there are problems, apparently running a mixed c++ / c# project, with the submission process. A solution to fix initial app certificaiton you are required to enable .net native-ization of the code.

After adding the solution mentioned here: microsoft/react-native-windows#4516 (comment), I cannot run my app anymore. The app literally gets stuck with a blank screen without errors being thrown in either terminal console or visual studio debug output. I tried using DotNetNativeVersion 2.2.3 and 2.2.8-rel-28605-00, added all Exception flags to be thrown, but literally nothing happens. Without having the fix applied, I can run and build my app without problems. That seems super strange to me but must somehow be related to the .net native-ization. Any ideas how this could be related?
