`EXCEPTION_ACCESS_VIOLATION` crash on Windows 10.

It generally seems to occur when navigating away from a screen that contains a video player, so it may have something to do with how the player state is disposed?

This is a typical log - the actual crash point is usually WindowsNativeBridge.nReadVideoFrame and usually mentions NativeVideoPlayer.dll.

While recording a video example of the crash I also encountered this. I believe this is the first time I have seen this particular error but it seems like it may be related.
