Selenium in Headless mode does not find page elements (Python)

Question

My code works normally without the headless activated, but as soon as I activate it stops working, it is as if it did not find the element on the page.

The problem is not in the code of the headless, because I have already sent it to take print and it works normally, the problem if gives from the moment I try to find some element of the page

from selenium import webdriver
from selenium.webdriver.support.ui import Select
from time import sleep

options = webdriver.ChromeOptions()
options.add_argument('--headless')

navegador = webdriver.Chrome(chrome_options=options)
navegador.get('https://www.instagram.com/')

insta = 'user'
senha2 = 'senha'

sleep(3)

login = navegador.find_element_by_xpath('//*[@id="loginForm"]/div/div[1]/div/label/input')
login.send_keys(insta)

sleep(2)
psw = navegador.find_element_by_name('password')
psw.send_keys(senha2)

sleep(2)
btn_logar = navegador.find_element_by_css_selector('.sqdOP.L3NKy.y3zKF')
btn_logar.click()

sleep(6)
navegador.save_screenshot('insta.png')
