Present CardSession multiple times

I'm developing a ticket app with Host card emulation. The session starts correctly the first time, but when trying to emulate a second ticket, after the first one has been read by the reader, or after the emulation has been canceled by the user, it doesn't work correctly for a while.

This is my CardSessionManager:

import CoreNFC

@available(iOS 17.4, *) class CardSessionManager { private static var cardSession: CardSession? = nil private static var presentmentIntent: NFCPresentmentIntentAssertion? = nil

static func initCardSession(_ accessCode: String) {
    cardSession?.invalidate()
    cardSession = nil
 
    let ProcessAPDU: (_: Data) -> Data = { capdu in
        var response = Data(accessCode.utf8)
        response.append(0x90)
        response.append(0x00)
        return response
    }
    
    Task {
        guard NFCReaderSession.readingAvailable,
              CardSession.isSupported,
              await CardSession.isEligible else {
            return
        }
        
        do {
            presentmentIntent = try await NFCPresentmentIntentAssertion.acquire()
            cardSession = try await CardSession()
        } catch {
            return
        }
        
        if let cardSession {
            for try await event in cardSession.eventStream {
                switch event {
                case .sessionStarted:
                    cardSession.alertMessage = String(localized: "Searching reader...")
                    try await cardSession.startEmulation()
 
                case .readerDetected:
                    cardSession.alertMessage = String(localized: "Reading...")
 
                case .readerDeselected:
                    cardSession.alertMessage = String(localized: "Successful reading!")
                    await cardSession.stopEmulation(status: .success)
 
                case .received(let cardAPDU):
                    cardSession.alertMessage = String(localized: "Communicating with reader.")
                    do {
                        try await cardAPDU.respond(response: ProcessAPDU(cardAPDU.payload))
                    } catch {
                        cardSession.alertMessage = error.localizedDescription
                    }
 
                case .sessionInvalidated(reason: _):
                    cardSession.alertMessage = String(localized: "Ending communication with reader.")
                    presentmentIntent = nil
 
                @unknown default:
                    break
                }
            }
        }
 
    }
}

}
