- Warnings due to obsolete Object.FindObjectsByType<T> usage and [SerializeReference] are logged when opening the Netcode for Entities setup scene
- Non-standard pointers cannot change Inspector values with arrow controls when crossing Inspector area
- No longer able to change the Toggle or Slider GameObjects' Target Graphic value and a NullReferenceException is thrown when the Target Graphic value is set to None at any point

Resolution Note:
This is the expected result with the Light Component API.
In HDRP, you need to use the HDAdditionalLightData API instead of the API in the Light component:https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@10.3/api/UnityEngine.Rendering.HighDefinition.HDAdditionalLightData.html#UnityEngine_Rendering_HighDefinition_HDAdditionalLightData_intensity
I know this may look like a workaround for now but we're working on a proper solution that will be soon available.
