Bug? Handle of Addressables.CleanBundleCache() cannot be released

'AsyncOperationHandle' which is return by 'Addressables.CleanBundleCache()' is always Valid but fail to be released.


Source Code

Code (CSharp):

1.             await Addressables.InitializeAsync();
2.  
3.             AsyncOperationHandle<bool> handle = default;
4.             try
5.             {
6.                 handle = Addressables.CleanBundleCache();
7.                 while (!handle.IsDone && handle.OperationException == null)
8.                 {
9.                     await System.Threading.Tasks.Task.Yield();
10.                 }
11.  
12.                 Debug.Log($"IsDone: {handle.IsDone}");
13.                 Debug.Log($"Status: {handle.Status}");
14.                 Debug.Log($"Has Exception?: {handle.OperationException != null}");
15.                 Debug.Log($"Result: {handle.Result}");
16.  
17.                 Debug.Log($"Handle Is Valid?: {handle.IsValid()}");
18.                 if (handle.IsValid())
19.                 {
20.                     Debug.Log($"Try release handle...");
21.  
22.                     Addressables.Release(handle);
23.  
24.                     Debug.Log($"Releasing handle Done...");
25.                 }
26.             }
27.             catch (Exception e)
28.             {
29.                 Debug.LogException(e);
30.             }

Debug Messages


The IsValid function of AsyncOperationHandle does not guarantee that the Handle can be released. I don't know if this is the intended result, but if not, this is a serious bug.
