    OS : windows
    Unity Version: 2021.3.13f1
    addressable: 1.21.1

    This is the code that calls Addressables.LoadAssetAsync and WaitForCompletion

    and in WaitForCompletion, i got this error from UnityWebRequest, and following this post, i tried to find the exact code to dispose of the web request,

    I found that in the addressable source code AssetBundleProvider.cs, there is a Dispose() in WebRequestOperationCompleted been called to that web request before IsAssetBundleDownloaded

    after that Dispose(), IsAssetBundleDownloaded continued to check the same UnityWebRequest and got the _unity_self null error.

    Any help will be thankful. Can i bypass this error by try-catch without any side-effect?

    same issue here with unity2013.3.13 + addressable1.21.1:

    ArgumentNullException: Value cannot be null.
    Parameter name: _unity_self
    UnityEngine.ResourceManagement.Util.UnityWebRequestUtilities.IsAssetBundleDownloaded
