Any ideas?
Exporting other demo projects and running them works fine

I have the very same problem. But currently have no fix available to me.

I’m having the same problem. Any luck?

Not really, I have stuck for multiple days and tried all these following:

  1. Complete clean Intermedia, DerivedCache, Saved in the project and re-package.
  2. Confirm WorldGridMaterial’s existence in Engine Content, Cook in editor and re-package.
  3. Disable r.MobileHDR and re-pacakge.
  4. Packaging on Mac OS. It also cannot run but I cannot confirm the message.

None of these worked for me. It’s very frustrating.
