PackagingResults: Error: Unknown Error, AutomationTool exiting with ExitCode=6 (6)

I’m getting PackagingResults: Error: Unknown Error, with AutomationTool exiting with ExitCode=6 (6) while trying to package a template project on UE5.6.1 for the Windows platform. The following is my generated log:

2. Copying the Hostfxr.dll to the automation tools folder

How to solve this error ???

Hey there @Sumant_Bag_1992! It seems like you could have run into an esoteric issue involving how the command for Unreal Built Tool works. I remember seeing a thread where a user had also named their project TEST and was having the same issue closely related to issue UE-74975.

500×500 2.84 KB

(This contains extra info on UE-74975) An acquaintacne ran into UE-74975 the other day: If you name your project “Test”, “Development” or a couple of other things, then UnrealBuildTool fails building it with the error message “ERROR: No target name was specified on the command-line.”. This command line will fail: "E:\Program Files\Epic Games\UE_4.22\Engine\Binaries\DotNET\UnrealBuildTool.exe" Test Win64 Development -Project=c:\temp\Test\Test.uproject c:\temp\Test\Test.uproject -NoUBTMakefile…

Do other projects build normally?

Thank you, I changed the folder name to something other than TEST, and it worked properly.
