Directory monitoring stops the system from responding to interactions

Question

I have an application that monitors a certain folder and checks if there is the creation of a new file if a new file is created triggering several processes on the system.

But when active monitoring seems it locks various processes and does not allow me almost any interaction with my system.

public void Monitoramento(){

    Path pastaOrigem;
    try {
        pastaOrigem = Files.createDirectories(Paths.get("C:\\monitoramento"));


    watcher = FileSystems.getDefault().newWatchService();


    pastaOrigem.register(watcher, ENTRY_CREATE);

    while (true) {

        WatchKey wk = null;
        try {

            wk = watcher.take();
        } catch (InterruptedException e) {
            throw new RuntimeException(e);
        }

        for (WatchEvent<?> event : wk.pollEvents()) {

            if (event.kind() == OVERFLOW) {
                continue;
            }

            WatchEvent<Path> ev = (WatchEvent<Path>) event;
            Path nomeArquivo = ev.context();
            Path arquivoOrigem = pastaOrigem.resolve(nomeArquivo);

            String arquivo = nomeArquivo.toString();

            if (arquivo.substring(0, 3).equals("vn")) {


               novoEvento ne = new novoEvento();


               ne.leituraArquivo(arquivoOrigem);

            }

        }

        if (!wk.reset()) {
            break;
        }
    }

    } catch (IOException ex) {
        Logger.getLogger(TelaPrincipal.class.getName()).log(Level.SEVERE, null, ex);

    } catch (Exception ex){
        ex.printStackTrace();
    }
}
