Creating AVAssetDownloadTask with URL received in `urlSession(_:assetDownloadTask:didFinishDownloadingTo:` failed

Hi, I have created an AVAssetDownloadTask and run resume() as in the title.
As a result, urlSession(_:task:didCompleteWithError:) is called immediately and returns (domain=NSURLErrorDomain code=-1=NSURLErrorUnknown) as error.

My understanding is that this URL is metadata that points to movpkg.
By creating an AVAssetDownloadTask with this URL, we can resume the DL from the continuation of the previous download.
In fact, there were times when it was possible. But during the development process, it started returning errors. Restarting the OS did not change the result.

I read the description of NSURLErrorUnknown.
This is the value returned when an unexpected event occurs. It is always recommended to contact Apple.
Please, I would appreciate your advice on how to resolve this issue.

This issue was confirmed by iPhone SE Gen 2, iOS15.7 and iPhone 12 mini, iOS16.2.
