Hi,

I’m trying to build .pak file by UE5.7.1 Project Launcher. But I get some error when packaging. Both mac and windows. There is my package config.

And there is the error log:

********** COOK COMMAND COMPLETED **********

A Zen file manifest must not exist when staging without IoStore. Did not expected to find /Users/apple/repos/UnrealProjects/HotUpdate/Saved/Cooked/Mac/HotUpdate/Metadata/zenfs.manifest. Ensure that legacy cooking with ZenStore disabled (bUseZenStore=false) was successful.

AutomationTool executed for 0h 1m 11s
AutomationTool exiting with ExitCode=1 (Error_Unknown)
RunUAT ERROR: AutomationTool was unable to run successfully. Exited with code: 1

I have tried that delet DerivedDataCached and Cooked folders. And I’m cooking a brand new empty projects.

I guess the error may be here but why it.

Has anyone else experience this? Any hints or tip would be appreciated a lot, thanks!
