I’m having this same issue right now with 4.13.1 when building for Win64

Hi ,

When you say you’re building, are you building through Visual Studio or attempting to Package the game through the editor?

Also, could you please provide a few things:

  • Logs from your projects Saved->Logs folder
  • Machine ID if you’re crashing and getting a crash reporter window, also ensure to hit Send & Close on the report.

Thanks
