UNUserNotificationCenter::requestAuthorization failed with NSCocoaErrorDomain

I try to using the module UserNotifications in swift project, to send notifications of my macos app.

I pack my app with nested bundle like:

/Application/MyApp.app 
  - Contents
    - Resources 
    - Frameworks
    - MacOS
        - my_binary
    - Notifier.app 
        - Resources 
        - Frameworks
        - Contents
        - MacOS
            - notifier_binary
                         

When I use cmdline to execute my notifier_binary, it's work fine. But when I execute it form my_binary, it will failed sometimes in api requestAuthorization, and the auth setting result will be not authed. But in current user's setting, it had been allowed.

The error message in log, I can't find anything useful in google result, I have no idea what this error message means.

2022-10-27 16:32:11.297912+0800 0x3ded     Error       0x0                  1697   0    notifier_binary: (UserNotifications) [com.apple.UserNotifications:Connections] [com.my.notifier] Getting notification settings failed with error: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.usernotifications.usernotificationservice was invalidated: failed at lookup with error 3 - No such process." UserInfo={NSDebugDescription=The connection to service named com.apple.usernotifications.usernotificationservice was invalidated: failed at lookup with error 3 - No such process.}

Here it's my swift code:

class NotiSender {
    let un = UNUserNotificationCenter.current()
    func sendNoti(){
        var waiting = true;
        un.requestAuthorization(options: [.alert, .sound]) {(authorized, error) in
            if authorized {
            } else if !authorized {
                Logger.error("user not authorized\n")
            } else {
                Logger.error("error: \(error?.localizedDescription)\n")
            }  
            waiting = false;          
        }

        while (waiting) {
            sleep(1);
        }

        un.getNotificationSettings{ (settings) in
            if settings.authorizationStatus == .authorized {
             // send my notifications
              .......
        }
}

@main
class AppDelegate: NSObject, NSApplicationDelegate {
    func applicationDidFinishLaunching(_ aNotification: Notification) {
        UNUserNotificationCenter.current().delegate = self
        let sender = NotiSender()
        sender.sendNoti()
        ......
    }
}

Did I miss some entitlements or app setting in Info.plist ? Or did I misuse the api?

Thanks for any help!!!
