Getting CoreMediaErrorDomain -15628 playback failure in iOS 26 (AVPlayer, HLS stream)

Hi,

After updating to iOS 26, our app is experiencing playback failures with AVPlayer. The same code and streams work fine on iOS 18 and earlier.

Error: Domain [CoreMediaErrorDomain] Code [-15628] Description [The operation couldn’t be completed.] Underlying Error Domain [(null)] Code [0] Description [(null)]

Environment: iOS version: iOS 26 Stream type: HLS (m3u8) with segment (.ts) files

Observed behaviour: We don’t have concrete steps to reproduce the issue, but so far, we have observed that this error tends to occur under low network conditions.
