How do I fix errors when packaging a Pixel Streaming project?

Following the above, I got to 1.3 Package your Project for Windows. From the main menu in the Unreal Editor, choose Files > Package Project > Windows (64-bit).
But here I get an error.
UATHelper: Packaging (Linux): RunUAT ERROR: AutomationTool was unable to run successfully. Exited with code: 134
PackagingResults: Error: AutomationTool was unable to run successfully. Exited with code: 134
PackagingResults: Error: Unknown Error
How can this be resolved? Not packaged.
