Cant pakage BP project an item with same key has already been added

when I try packaging my project I get this error ERROR: System.ArgumentException: An item with the same key has already been added.
I can’t seem to figure out why this is happening I’ve looked at multiple posts even made a new project and am still getting the error.

Ok I figured it out I had to move all my content to a new project

did not work for me An item with the same key has already been added. still occurs :frowning:
