Greetings.
The two pictures I posted first are of the crash messages when starting a packaged game using Async Thread or Async Thread + Event Driven Loading, in 4.17 release however it just goes to a black screen and hangs.
Game modes and starting maps etc are setup properly, I am currently installing the 4.17.1 hotfix and will test first if there is any change in behaviour there. I’ll return with results in a while.
