Hello Xerdi296,

I have a couple questions about your project to help me investigate further

Have you deleted your saved and intermediate folders?
Are you using any third party plugins?
Does this issue affect one project or multiple projects you are packaging?

Thanks!

Hi ,
I have a similar problem, I tried to package a topdown sample project and following errors occurred:

UATHelper: Packaging (Windows (64-bit)): ERROR: UBT ERROR: Failed to produce item: D:\UnrealEngine4.19\Engine\Plugins\Runtime\PhysXVehicles\Binaries\Win64\PackageTest-PhysXVehicles.lib
PackagingResults: Error: UBT ERROR: Failed to produce item: D:\UnrealEngine4.19\Engine\Plugins\Runtime\PhysXVehicles\Binaries\Win64\PackageTest-PhysXVehicles.lib

Hope you can help me out…

I had a similar error, also with “A conflicting instance of AutomationTool is already running” message. What solved for me was:

delete the Intermediate folder
right click on the .uproject file
Generate Visual Studio project files

Thanks to the answer on this thread.
