UnrealEd Packaging Error!

I tried packaging my game but i kept getting this error:
UATHelper: Packaging (Windows (64-bit)): ERROR: Unable to instantiate module ‘UnrealEd’: Unable to instantiate UnrealEd module for non-editor targets.
UATHelper: Packaging (Windows (64-bit)): (referenced via Target → NativizedAssets.Build.cs → ToonWars.Build.cs → UMGEditor.Build.cs → Sequencer.Build.cs)

I don’t know what that means so I can’t look for the error. I’ve packaged the game before and I didn’t get this error, and I reverted the work done on the widgets, which is all I’ve really changed since the last build.
Can someone help?
