Puppeteer click on next(Publicar) blocks everything

Question

After fill the from with puppeter and try to submit, it is like stops working, can anyone help me to know what is happening? here is my code. If you remove the "await page.click('.btnSiguiente');" line, it works and the screenshot is ok, but on submit, something happens.

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch({
         dumpio: true
    });
  const page = await browser.newPage();


  await page.goto('https://www.pasion.com/textos-del-anuncio/?p=albacete&l=Rivas-Vaciamadrid&c=581&demandax=&x=33&y=17');

  await page.type('#titulo', 'test!'); // Titulo
  await page.select('#elform > div.formColIzq.texto > select:nth-child(9)', 'chica'); // Genero
  await page.select('#elform > div.formColIzq.texto > select:nth-child(10)', 'chico'); // Busco
  await page.type('#edad', '41'); // Edad
  await page.type('#nombre', 'user'); // Nombre
  await page.type('#email', '[email protected]'); // Email
  await page.type('#repemail', '[email protected]'); // Repetir Email
  await page.type('#telefono1', '666676151'); // Telefono
  await page.type('#texto', 'Lorep ipsun'); // Anuncio
  await page.select('#horario1', 'a la hora de comer'); // Horario
  await page.select('#duracion', '30'); // Caducidad
  await page.click("#acepto_condiciones_uso_y_politica_de_privacidad",{clickCount:1}); // Terminos y condiciones
  await page.click('.btnSiguiente');
  await delay(1500);
  
  await page.screenshot({ path: 'test.png' });
  await browser.close();
})();

function delay(time) {
   return new Promise(function(resolve) { 
       setTimeout(resolve, time)
   });
}
