AVAssetExportSession is not working on Iphone 16 pro max.

My App is live on app store , user are using it with iPhone 16 pro max and they are getting Operation Stopped while combining videos and audios only specifically on iPhone 16 pro max , on every other device its working fine. And When i adding AVAssetExportPresetPassthrough it able to combine videos and audios but not respecting the encoding and without audio.

        NSArray *compatiblePresets = [AVAssetExportSession exportPresetsCompatibleWithAsset:composition];
        if ([compatiblePresets containsObject:AVAssetExportPresetHighestQuality]) {
            presetName = AVAssetExportPresetHighestQuality;
        } else if ([compatiblePresets containsObject:AVAssetExportPreset1920x1080]) {
            presetName = AVAssetExportPreset1920x1080;
        } else if ([compatiblePresets containsObject:AVAssetExportPreset1280x720]) {
            presetName = AVAssetExportPreset1280x720;
        } else {
            presetName = AVAssetExportPresetPassthrough;
        }
    } else {
        presetName = AVAssetExportPreset1280x720;
    }

Update: It's only happening when user is recording from iPhone 16 pro max ... previously pre-recorded videos are working fine.

Our engineering teams need to investigate this issue, as resolution may involve changes to Apple's software. I'd greatly appreciate it if you could open a bug report, include a small Xcode project that can be used to reproduce the problem and directions for using the text project, and post the FB number here once you do.

I am encountering a similar issue with a code that works perfectly on all devices except the iPhone 16 Pro Max: I observe a significant random slowdown that occurs when using AVAssetWriter.

The issue only appears at the launch of the application (e.g., when it hasn't been used for several hours).

I am encountering a similar issue when using AVFoundation to compress videos shot by iPhone16 pro max, The Audio compression always fails and prompts that the operation cannot be completed, very sad.
