Hi,
thank you for raising the issue. Do you know if this could be related to your other question about a crash on iOS 16?
The reason for the other crash is that no active Source is loaded in the Player when the seek operation is called.
We released 3.31.0-b.1 yesterday as a pre-release version which should contain a fix so it no longer crashes. Maybe you could give it a shot and try to reproduce the crash with this beta version. (Please note that this is a pre-released version which might still contain bugs and untested features).
If it still crashes, it would be great to get more insights about the reproduction steps that lead to this crash. In addition what does -[AVPlayerController actuallySeekToTime] stand for? As far as I know this is not a (public) system type.
