This occurred with both Development and DebugGame build configurations.

In the game's console I tried both "quit" and "exit" and reproed the crash. The crash also occurs via Alt + F4 or closing via the 'X' in the game window.

I attached GDB to the process and the Core dump file and attaching them to the Jira. My log is from the DebugGame build.

Steps to Reproduce


  1. Create a code project using first person template on a Windows machine
  2. Package the project for Linux
  3. Transfer the packaged project to a Linux machine
  4. Run the project from a terminal window and close it.

Game freezes for a second, then a crash is observed in the terminal after the game window closes.
