Research direction
Start in ScannerViewController.swift at setupCaptureDevice() around line 314, following the stack trace through camera permission handling and session setup. Reproduce startup on iOS 15 and iOS 16 devices, then verify that capture sessions no longer raise the reported active-color-space exception during configuration.

Description
Hi!
I'm seeing some crashes when starting a capture session - on various devices using iOS 15 and iOS 16.
NavigationView {
VStack {
CodeScannerView(
codeTypes: [.qr],
scanMode: .oncePerCode
) { response in
if case let .success(result) = response {
onFindQRCode(result.string)
}
}
.padding(.horizontal, 16)
.padding(.bottom, 24)
.aspectRatio(1, contentMode: .fit)
// More view elements
}
}
