Hi - I’m very much a newbie, and I’ve created something in UE 5.1 which I’m kinda proud of. But when I try and package it for Windows it fails, and the message in red says.

PackagingResults: Error: System.ArgumentException: An item with the same key has already been added. Key: TwinmotionToUnrealContent

I’ve searched here for possible solutions but haven’t found anything. Same for web.

Is anyone please able to help me to get back up and jump the final hurdle?!

Thanks

same key has already been added
that mean “Engine/Plugins/xxx/” and “{YourProject}/Plugins/” has same Plugin

like
“Engine/Plugins/Marketplace/TwinmotionToUnrealContent”
“{YourProject}/Plugins/TwinmotionToUnrealContent”
delete one :grin:
