Crash 4.18.2, TCP Messaging Plugin required in shipping

  • create a basic code C++, desktop, maximum quality, no starter content project
  • make a test level and assign it in project settings as default
  • change supported platforms to windows only
  • change build configuration to shipping
  • disable plugins (link)
  • package project → windows → windows (64 bit)

once you launch the exe that is generated, the game will crash with a “Fatal Error” and no explanation and no crash log

Just had the same issue. Had to spend about 3 hours investigating what was broken, until I found out about that plugin.
