BUILD FAILED

Nod24,

Please follow these instructions and your issue should be resolved:

  • Open up the Epic Games Launcher
  • Click on the Library tab
  • Click on the yellow and black downward arrow beside Launch
  • Click on Options
  • Make sure that there is a check-mark beside ‘Editor symbols for debugging’
  • Press Apply

Once you’ve done that, it should update the editor for you and this issue should go away. Please let us know if it does not.

Thanks!
