Error Domain=NFCError Code=100 “Tag connection lost” UserInfo={NSLocalizedDescription=Tag connection lost})

we are using the STMicroelectronics/STNFCSensor tag, the tag configuration is Block Size: 4 Memory size in blocks: 2048 memory size in bytes: 8192 tag type: iso15693

Below i added my code

func readSingleBlock(to tag: NFCTag, blockNumber: Int, completion: @escaping (Data) -> Void) {
        
        bfprint("NFC_Tag enter extendedReadSingleBlock blockNumber: \(blockNumber)")
        
        if case let .iso15693(tagIso15693) = tag {
            
            tagIso15693.extendedReadSingleBlock(requestFlags: [.highDataRate], blockNumber: blockNumber) { result in
                bfprint("NFC_Tag extendedReadSingleBlock \(result)")
                switch result {
                case .success(let data):
                    self.retryAttempt = 0
                    bfprint("NFC_Tag Success tag response:", "\(data), ")
                    completion(data)
                case .failure(let error):
                    
                    if self.retryAttempt > 5 {
                        bfprint("NFC_Tag failure: \(error) \(error.localizedDescription) ")
                        self.session?.invalidate(errorMessage: error.localizedDescription)
                    } else {
                        self.retryAttempt += 1
                        bfprint("NFC_Tag failure retryAttempt: \(self.retryAttempt) ")
                        self.retryConnection()
                    }
                }
            }
        }
    }
    
    func retryConnection() {
        
        
        guard let session,
        let tag = self.tag else { return }
        session.connect(to: tag) { [weak self] (error) in
            if let error = error {
                print("Retry connection error: \(error.localizedDescription)")
                self?.session?.invalidate(errorMessage: "Retry connection error: \(error.localizedDescription)")
                return
            }
            self?.readNfcTag(tag: tag)
        }
    }

extendedReadSingleBlock function giving error "NFCError Code=100 “Tag connection lost”
