Description

This was occurring when I quit via the Quit button in the Main Menu GUI. I also repro'd this using the "Quit" command in the console.

I found this on Linux, but this was repro'd on Mac and Windows by other testers.

Attaching logs for all three platforms and the backtrace while GDB was attached to the game on Linux. (Callstack field is from GDB)

Steps to Reproduce

Setup:

  • In the Epic Games Launcher, download create a 4.17 version of the PlatformerGame sample
  • Open PlatformerGame in the editor.
  • Set the packaging build configuration to development
  • File > Package Project > Win64.

Repro:

  • Copy the packaged PlatformerGame from the Networkshare listed in the comments:
  • Open the packaged project
  • In the Main Menu, click the "Quit" button.

Result:
Game hangs/freezes then crashes.

Expected:
Game exits gracefully.

Frequency:
100%
