NoSuchElementError with Selenium using RubyMine after trying all element attributes

Question

I am tying to write some tests for this website: https://roomy-fire-houseboat.glitch.me/ but unable to find any elements. I can launch the website then add 5 seconds of sleep.

Here is the error in RubyMine:

Selenium::WebDriver::Error::NoSuchElementError: no such element: Unable to locate element: {"method":"css selector","selector":"#number"}
  (Session info: chrome=123.0.6312.59); For documentation on this error, please visit: https://www.selenium.dev/documentation/webdriver/troubleshooting/errors#no-such-element-exception

Here is the current line, I am using to find the text box on the website.

driver.find_element(:id, 'number')

I have also tried :css and :xpath.

When I inspect the element, I get the following:

id = "number" type = "text"

selector = #number

xpath = //*[@id="number"]

Not sure what your program is, I have written the following program and it works fine for me.

require 'selenium-webdriver'

driver = Selenium::WebDriver.for :chrome

driver.navigate.to 'https://roomy-fire-houseboat.glitch.me/'

driver.find_element(id: 'number').send_keys '2'

driver.find_element(id: 'start').click

sleep 10

Can you try this and let me whether you face any problem.
