Selenium wait for the page to load completely

Even if I followed documentation sample, I'm still getting:

OpenQA.Selenium.NoSuchElementException: 'no such element: Unable to locate element: {"method":"css selector","selector":"#username"}
  (Session info: chrome=122.0.6261.112); For documentation on this error, please visit: https://www.selenium.dev/documentation/webdriver/troubleshooting/errors#no-such-element-exception'

OpenQA.Selenium.NoSuchElementException: 'no such element: Unable to locate element: {"method":"css selector","selector":"#username"}
  (Session info: chrome=122.0.6261.112); For documentation on this error, please visit: https://www.selenium.dev/documentation/webdriver/troubleshooting/errors#no-such-element-exception'

Below my code:

private void button2_Click(object sender, EventArgs e)
{
    driver.Navigate().GoToUrl("https://mywebsiste.com/login");

    // Wait for the page to load completely
    WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10))
    {
        PollingInterval = TimeSpan.FromMilliseconds(300),
    };
    wait.IgnoreExceptionTypes(typeof(NoSuchElementException));

    wait.Until(d =>
    {
        // Login
        driver.FindElement(By.Id("username")).SendKeys("myusername");
        driver.FindElement(By.Id("password")).SendKeys("mypassword");
        driver.FindElement(By.ClassName("remember")).Click();
        driver.FindElement(By.Id("loginSubmit")).Click();
        return true;
    });
}

private void button2_Click(object sender, EventArgs e)
{
    driver.Navigate().GoToUrl("https://mywebsiste.com/login");

    // Wait for the page to load completely
    WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10))
    {
        PollingInterval = TimeSpan.FromMilliseconds(300),
    };
    wait.IgnoreExceptionTypes(typeof(NoSuchElementException));

    wait.Until(d =>
    {
        // Login
        driver.FindElement(By.Id("username")).SendKeys("myusername");
        driver.FindElement(By.Id("password")).SendKeys("mypassword");
        driver.FindElement(By.ClassName("remember")).Click();
        driver.FindElement(By.Id("loginSubmit")).Click();
        return true;
    });
}

What am I doing wrong?

For some reason looks like that the implicit way:

private void button2_Click(object sender, EventArgs e)
{
    driver.Url = "https://mywebsiste.com/login";

    driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10);

    driver.FindElement(By.Id("username")).SendKeys("myusername");
    driver.FindElement(By.Id("password")).SendKeys("mypassword");
    driver.FindElement(By.ClassName("remember")).Click();
    driver.FindElement(By.Id("loginSubmit")).Click();
}

private void button2_Click(object sender, EventArgs e)
{
    driver.Url = "https://mywebsiste.com/login";

    driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10);

    driver.FindElement(By.Id("username")).SendKeys("myusername");
    driver.FindElement(By.Id("password")).SendKeys("mypassword");
    driver.FindElement(By.ClassName("remember")).Click();
    driver.FindElement(By.Id("loginSubmit")).Click();
}

Works perfectly, also if I don't have idea about how I randomly decited to use this method, for go on, thinking that driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10); just add a 10 seconds pause before execute next commands, but looks like that this one "wait max 10 seconds" but if he can't perform operations before, it do it So I suppose that it automatically handle the situation
