Extending a Hololens Unity project with Vuforia tracking makes it impossible to build

Vuforia SDK Version: 8.3.9 - Description with steps to reproduce: I created a Hololens project in Unity 2019. It builds and runs fine. Then I tried adding an Vuforia object target (along with the camera script). Now the project won't build (though it does run without errors in play mode). I've narrowed down that the issue starts when enabling Vuforia support in the player settings. When I disable it, it works again. I will attach the whole console log from the build below. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Reference Rewriter found some errors while running with command "--target=Temp\StagingArea\Data\Managed\Assembly-CSharp.dll" "--target=Temp\StagingArea\Data\Managed\Microsoft.MixedReality.Toolkit.Services.SceneSystem.dll" [ list continues on for many lines ] Reference rewriter: Error: type `UnityEngine.Experimental.Rendering.RenderPipeline` doesn't exist in target framework.
