Build Player Content fails with: NullReferenceException: Object reference not set to an instance of

I'm getting ready to make a test build of a project we're using addressables for, but "build player content" dies with

NullReferenceException: Object reference not set to an instance of an object
LinkXmlGenerator.Save (System.String path) (at Library/PackageCache/com.unity.addressables@0.5.3-preview/Editor/Build/LinkXMLGenerator.cs:29)

UnityEditor.GenericMenu.CatchMenu (System.Object userData, System.String[] options, System.Int32 selected) (at C:/buildslave/unity/build/Editor/Mono/GUI/GenericMenu.cs:121)

Is anyone else having issues getting the current version to build?

 

I'm seeing this as well when trying going to Addressables window, Build > Build Player Content, and then it crashes during the build. Am I missing a setting somewhere?

 

Had this as well after the import from 0.4.8 to 0.5.3, only deleting everything and readd addressables again and setup the groups again solved it for us.

 

@MNNoxMortem Thank, i'll give it a try.
