App freezes when built with Xcode 16 on iOS 18, but not on iOS 17 or lower, or with Xcode 15 on iOS 18

I'm experiencing an issue where my app freezes when built with Xcode 16 on iOS 18.

Additional Information:

• The issue does not occur when building the app with Xcode 16 on iOS 17 or lower.
• The issue does not occur when building the app with Xcode 15 on iOS 18.
• The CPU usage spikes to 100% when the app freezes.
• The app specifically freezes after the code runs into .sink(receiveValue:).

Here is the relevant code snippet:

    @Published var selectedCardData: CardData?
    @Published var selectedRootTab: RootViewTab = .statement

    override func load() {
        state = .loading
            
        $selectedCardData.ignoreNil()
            .removeDuplicates()
            .map { [unowned self] cardData in
                $selectedRootTab.filter { $0 == .statement }
                    .first()
                    .map { _ in cardData }
            }
            .switchToLatest()
            .sink(receiveValue: { value in
                print(value) // value not nil
                print("Execution reaches this point and the app freezes (CPU 100%).")
            })
            .store(in: &cancellables)
    }

Are there any known changes in iOS 18 or Xcode 16 that might affect this code?
