        .Where(x => !x.IsAbstract && !coreAssemblyNames.Contains(x.Assembly.GetName().Name))
        .Select(x => PackageInfo.FindForAssembly(x.Assembly))

Hi @FADEFALCON, Can you please provide more info on how you fixed it? I am having the same issue but don’t understand what you did.

When I try to build Android on Unity, my build fails with same error message:

NullReferenceException: Object reference not set to an instance of an object
Unity.Services.Core.Editor.LinkFileGenerator+<>c__DisplayClass12_0.<UnityEditor.Build.IUnityLinkerProcessor.GenerateAdditionalLinkXmlFile>b__5 (System.Type x) (at Library/PackageCache/com.unity.services.core@1.9.0/Editor/Core/Linker/LinkFileGenerator.cs:114)
