I pack a project using shipping build on UE5 5.5 . I receive this error warning log.

UATHelper: Packaging (Windows): LogWindows: Warning: Failed to set completion port for job object “UE.ShaderCompileWorker.JobGroup”: The parameter is incorrect.

Now my packed build is half in size. Help me remove this warning and explain what cause it. is it a bug? The cook time is so fast, is it even cooked ?

Hi, I had the same problem as you and I managed to solve it.

I had to choose a new location to store the game in my files because I had this bug on my second version.

I hope I was able to help you.

hi, thank you for replying. what do you mean by choosing new location. do I change the project file location or the destination of packing ?

I migrated all the useful assets to another project, which was newly created, and then found that they could be packaged.
