Mac | 4.27.0 - ERROR: Missing precompiled manifest for 'Launch'

Hi there! Having some issues while trying to build for Mac, hoping someone can help :slight_smile:

Essentially, I get this error when trying to package for either Shipping or Development

ERROR: Missing precompiled manifest for ‘Launch’

I’ve tried every solution I could find.

  • Attempted to Cook Content before building
  • Set Cook Content to Always in packaging settings
  • a few others, nothing worked.

I’m able to package this same project with Windows & Linux, so I’m not sure what’s happening, but I know it’s specific to Mac.

I’m using the launcher version of UE4 on Mac/Windows & using source on linux. Also, I’m able to create & package a blank project on Mac just fine. Super confused, would very much appreciate any help!
