[4.8p3] blank BP project crash at creation and when closing

Hey ,

The crash is gone (woohoo !) but i still can’t package the game properly:

The packaging process goes very well, no error, but i still get no binaries in my packaged directory, and when i try to launch the main exe, i get a black screen game in preview 4 (in preview 3 the game closed instantly, in p4 it remains open).

Repro is simple (on my computer at least): brand new blank blueprint project, no starter content, then select windows only as supported platform, then package for win64.
