Springboard crash when trying to add Control Widget

Xcode 16, iOS 18 official release. On both my phone and simulator, when I build the release build of my app, when I go to control center and select "Add a Control", springboard crashes (see attached crash log).

Somehow this does not happen in debug config, with debug config (which does have a different bundle ID but everything else is the same) I'm able to add the control widget just fine.

The widget code is taken directly from the Apple docs:

struct WidgetTestWidgetControl: ControlWidget {
    static let kind: String = "com.myapp.WidgetTestWidget"

    var body: some ControlWidgetConfiguration {
        AppIntentControlConfiguration(
            kind: Self.kind,
            provider: Provider()
        ) { value in
            ControlWidgetToggle(
                "Start Timer",
                isOn: value.isRunning,
                action: StartTimerIntent(value.name)
            ) { isRunning in
                Label(isRunning ? "On" : "Off", systemImage: "timer")
            }
        }
        .displayName("Timer")
        .description("A an example control that runs a timer.")
    }
}

extension WidgetTestWidgetControl {
    struct Value {
        var isRunning: Bool
        var name: String
    }

    struct Provider: AppIntentControlValueProvider {
        func previewValue(configuration: TimerConfiguration) -> Value {
            WidgetTestWidgetControl.Value(isRunning: false, name: configuration.timerName)
        }

        func currentValue(configuration: TimerConfiguration) async throws -> Value {
            let isRunning = true // Check if the timer is running
            return WidgetTestWidgetControl.Value(isRunning: isRunning, name: configuration.timerName)
        }
    }
}

struct TimerConfiguration: ControlConfigurationIntent {
    static let title: LocalizedStringResource = "Timer Name Configuration"

    @Parameter(title: "Timer Name", default: "Timer")
    var timerName: String
}

struct StartTimerIntent: SetValueIntent {
    static let title: LocalizedStringResource = "Start a timer"

    @Parameter(title: "Timer Name")
    var name: String

    @Parameter(title: "Timer is running")
    var value: Bool

    init() {}

    init(_ name: String) {
        self.name = name
    }

    func perform() async throws -> some IntentResult {
        // Start the timer…
        return .result()
    }
}

However in a fresh project I am able to add this widget code and it works completely fine in both debug and release. How can I fix this?

This is clearly affecting many apps and is the 'fault' of the app, see these threads: https://www.reddit.com/r/ios/comments/1fiqrd7/ios_18_control_center_keeps_crashing_when_trying/ https://discussions.apple.com/thread/255759997?sortBy=rank
