I'm testing the following configuration on macOS:
Modality: NONE
StageStyle: UTILITY
FullScreen: yes

Both with the current master, as well as this PR, I can confirm your observation that a non-fullscreen window shows up, and when it's closed, it freezes the application.

However, I think we're testing unsupported configurations here. These are definitively bugs, because unsupported configurations should not crash or freeze the application. What we should probably do is collect these artifacts in a bug ticket.
