What causes 'A valid type has not been set for this stream or a stream that it dependes on' exception during video playback

We do use MediaPlayerElement in UWP to play videos. However, occasionally (the occurance seems to be rare), the video which is working normally in any other way fails with following exception:

A valid type has not been set for this stream or a stream that it dependes on. (Exception from HRESULT 
0xC00D6D60)

What can cause this exception in our case? How to prevent it?

Edit - added snippet according to RoyLi comment:

This is how we create MediaPlaybackItem.

                StorageFile manifest_file = await Storage.MovieManifestFile(mi.UserGUID, mi.OrderItemGUID);

                amscr = await AdaptiveMediaSource.CreateFromStreamAsync(await manifest_file.OpenReadAsync(), new Uri(mi.MPDManifestUrl), "application/dash+xml");

                MediaSource converted_amscr = MediaSource.CreateFromAdaptiveMediaSource(amscr.MediaSource);

                MediaPlaybackItem ampi = new MediaPlaybackItem(converted_amscr);

The video source is MPEG-DASH stream protected with PlayReady. The issue was reproduced only on some devices and it happened not just for MPEG-DASH, but also for PIFF files.

After creating the MediaPlaybackItem, we simply use it as source for MediaPlayerElement.

 me.MediaPlayer.Source = ampi;
 me.MediaPlayer.Play();
