I have tried the methods that apparently worked for other and in my tessing narrowed the cause of the packaging faliure is linked to the Landmass plugin built into unreal engine, normaly if this were the case i would just un tick the plugin and find another way but sadly its vital to my project.

here is the output log, like i said i know its caused by the landmass plugin but i have no clue how to fix, i even tried ExcludeEditorContentFromBuild and nothing works, hopefully someone has this problem and fixed it
