Crash on startup in Release Mode

Not able to get under the debugger for some reason, but appears in release mode (at least for x64) that the application just continually hangs on initialization or the welcome page and restarts (there is code to trigger restart in XAML Studio, so that last part is probably a loop now).

According to log:
```
