Hi Ed, I am having the same issue about 2 weeks, so far couldnt solve the issue.
May you bit open how to fix up redirectors in the project? Which content folder do we need to right click and so on?
Also same for deleting the config file.
I currently not able to package my project, besides it is not possible to package even a new blank project which I already tried. Always getting the same error as,
PackagingResults: Error: System.ArgumentException: An item with the same key has already been added.
UATHelper: Packaging (Windows (64-bit)): AutomationTool exiting with ExitCode=1 (Error_Unknown)
UATHelper: Packaging (Windows (64-bit)): BUILD FAILED
PackagingResults: Error: Unknown Error
LogSlate: Took 0.000104 seconds to synchronously load lazily loaded font ‘…/…/…/Engine/Content/Slate/Fonts/DroidSansMono.ttf’ (77K)
Any help would be a grand. .
