We're getting this crash in our app and suspect it's a bug in CFNetwork. We use Alamofire (latest version). Seems from the stack something with trying to handle a request from the background? Is this issue known / seen by others?Here is a snippet of the crash log:Incident Identifier: 6EC9B455-E406-4E40-A511-79B474349DE4CrashReporter Key: b331b621d790ae666f815ef9895a2a505399aca4Hardware Model: iPhone11,8Process: Stream [25811]Path: /private/var/containers/Bundle/Application/1DCF7A7E-C6A9-4190-B478-905442C501F7/Stream.app/StreamIdentifier: com.microsoft.streamVersion: 7482 (1.1.12)AppStoreTools: 11C29AppVariant: 1:iPhone11,8:13Code Type: ARM-64 (Native)Role: Non UIParent Process: launchd [1]Coalition: com.microsoft.stream [4167]Date/Time: 2020-01-21 21:38:08.5997 +0100Launch Time: 2020-01-21 21:30:37.2939 +0100OS Version: iPhone OS 13.3 (17C54)Release Type: UserBaseband Version: 2.03.07Report Version: 104Exception Type: EXC_BAD_ACCESS (SIGBUS)Exception Subtype: KERN_MEMORY_ERROR at 0x0000000104974000 FS pagein error: 1 Operation not permittedVM Region Info: 0x104974000 is in 0x104974000-0x10497c000; bytes after start: 0 bytes before end: 32767 REGION TYPE START -

We have an HLS video stream which is failing to play in AVPlayer but plays on ExoPlayer. AVPlayer throws the above error code, which we cannot find any reference to or help with understanding what exactly is AVPlayer doing (or finds unacceptable with the stream). We'd like to know what causes this error to be thrown. We see this when HLS segments are authored from an MP4 with some questionable I and P frame data near the end of the container. The error is thrown on iOS 14.7.1 AVPlayer.

When I attempt to log network requests with the new "Network" profiling template with "Http Traffic" instrument (Instruments version 13.2.1), I get network connections data on my iphone, but no HTTP traffic data. I'm running with iOS 15.3 on iphone 11, and running macos 12.2 I get the warning that sensitive data will be recorded in the trace, but I never get any actual events posted there. I also don't get any kind of warnings or errors from Instruments telling me why it might have issues recording anything. I get these data from Charles just fine (when I properly setup Charles as a proxy). From what I read, Instruments HTTP Traffic should "just work", but for me it's not and not telling me why. Is there any way to diagnose why I'm not getting any Http traffic data in my recordings? I've disabled web protection on the phone (Microsoft Defender), which was necessary for Charles to work, but I never needed to install any certificate for instruments (or are there any instructions to do so), so I assume there is a default certificate that is used to encrypt web traffic which instruments can decrypt. I'd really like to use this tool!
