Javascript executor unable to scroll due to activities on page (Selenium automation)

Below is my script testing various scenarios with Javascript executor. However, it fails on the last step, which was to scroll. I noticed that after navigating to the page, the elements were taking an exceptionally long time to load. I tried several wait options but didn't work.

package UI;
import java.time.Duration;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import io.github.bonigarcia.wdm.ChromeDriverManager;
public class JavascriptExecutor1 {
public static void main(String[] args) {
// TODO Auto-generated method stub
//System.setProperty("webdriver.chrome.driver","C:\\browserdrivers\\chromedriver.exe");
ChromeDriverManager.getInstance().setup();
ChromeDriver driver = new ChromeDriver();
driver.get("https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_alert");
//driver.manage().window().maximize();
// accept popup
WebDriverWait wait = new WebDriverWait(driver,Duration.ofSeconds(30));
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//*[@id=\"accept-choices\"]"))).click();
JavascriptExecutor jxect = (JavascriptExecutor) driver; // Like API to javascript command library
// This will print the title of the page.
String script = "return document.title;"; // The script is title display as string
String title = (String) jxect.executeScript(script); // Tells javascript to execute the script n save it in title variable
System.out.println(title);  //Printing out whatever script we we executed that is saved in title variable.
// We want to click the button
driver.switchTo().frame("iframeResult");
jxect.executeScript("myFunction()");
//Thread.sleep(2000);
driver.switchTo().alert().accept();
//To highlight a button
WebElement button = driver.findElement(By.xpath("/html/body/button"));
jxect.executeScript("arguments[0].style.border='5px solid red'", button);
//to scroll
driver.navigate().to("https://www.w3schools.com/");
WebElement getstarted = driver.findElement(By.xpath("/html/body/div[4]/div/div[1]/div[17]/div/a"));
jxect.executeScript("argument[0].scrollintoview(true);", getstarted); 
}
}

You have typo in method scrollintoview - it should be scrollIntoView.
And typo in argument variable - it should be arguments

Code below works for me:
<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

driver.get("https://www.w3schools.com/");
WebElement getStarted = driver.findElement(By.cssSelector("#getdiploma"));
jxect.executeScript("arguments[0].scrollIntoView(true);", getStarted);

<!-- end snippet -->
