Packaging fails with "the same key has already been added

Hello.
When I run the packaging on Unreal Engine, it fails with the error “An item with the same key has already been added”.
The cause is probably because it is a cloned package.
Removing “Intermediate”, “DerivedDataCache” and “Saved” had no effect.

I think I need to remove the .target file.
But When I search for .target, I see many files.
Can I delete all of these?

UE 4.27.2

Running the packaging on another PC succeeds

When I had this, there were two copies of one plugin.

Take a look in the engine plugins folder.

Hi, ClockworkOcean
A careful check of the plugins folder revealed the same plugins in the Marketpalce and Runtime folders in the Plugins folder, respectively!
I had no idea that a plugin that was not enabled would affect me!

Finally my project was packaged!
Thank you very much. :laughing:
