Unity 2020.3 URP - Loading PostProcessing Volume Profile at Runtime

Hi,

I am trying to switch global post-processing settings for my scene by loading PostProcessingVolumeProfiles into my PostProcessingVolume. Currently I have two Profiles - Test.asset and MegaBloom.asset. Switching the Profile in Unity Editor works flawlessly. In Script it does not work:

 public class PostController : MonoBehaviour
 {
     [SerializeField] private Button _profileButton;
 
     private Volume volume;
 
     private void Start()
     {
         volume = gameObject.GetComponent<Volume>();
 
         _profileButton.onClick.AddListener(ChangeProfile);
     }
 
     private void ChangeProfile()
     {
         VolumeProfile testProfile = new VolumeProfile();
 
         testProfile = Resources.Load("Assets/Scenes/Core/MegaBloom.asset") as VolumeProfile;
         testProfile.name = "MegaBloom";
 
 
         volume.profile = testProfile;
         Debug.Log("Post: " + volume.profile.name);
     }
 }

The profile has no effect (in this case changing the Bloom intensity) and trying to access the name member causes an exception: NullReferenceException: Object reference not set to an instance of an object

This seems to be a hint that the asset is not loaded as a VolumeProfile or the type of the asset should not be UnityEngine.Rendering.VolumeProfile but something different I have not found.

Thanks! Danny
