And here is my code:

    System.setProperty("webdriver.chrome.driver", "C:\\Users\\nrapoo\\Desktop\\chromedriver.exe");
    WebDriver driver = new ChromeDriver();
    WebDriverWait wait=new WebDriverWait(driver, 20);
    driver.get("http://cedd-wb/enter.htm");
    driver.manage().window().maximize();
    driver.findElement(By.xpath("//*[@id=\"username\"]")).sendKeys("seden");
    driver.findElement(By.xpath("//*[@id=\"pword\"]")).sendKeys("hello1");
    driver.findElement(By.xpath("//*[@id=\"login_form\"]/div[3]/button")).click();      
    driver.findElement(By.xpath("//*[@id=\'menuDropdown-enq\']")).click();
    Thread.sleep(300L);
    driver.findElement(By.xpath("//ul[@class='list-unstyled di-block m-y-10']//a[contains(text(),'People')]")).click();
    driver.switchTo().frame("browsePeopleFrame");
    Thread.sleep(500L);
    driver.findElement(By.xpath("//*[@id='quickselect']")).sendKeys("ATNS");        
    Thread.sleep(500L);
    driver.findElement(By.xpath("//*[@id=\"peopleSelectFormBean\"]/div[2]/div[1]/div/div/div/span[2]/button/span")).click();
    driver.switchTo().defaultContent();
    WebElement namingwait;
    namingwait = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//ul[@id='categories-tabs']//a[contains(text(),'Naming')]")));
    namingwait.click();
    driver.switchTo().defaultContent();
    WebElement reservedname;
    reservedname = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id=\"category-114\"]/div[1]/a[1]")));
    reservedname.click();
    Thread.sleep(900L);
    driver.findElement(By.xpath("//*[@id=\"content\"]/section[3]/div/article/header/ul/li/a")).click();
    char[] chars = "abcdefghijklmnopqrstuvwxyz".toCharArray();
    StringBuilder sb = new StringBuilder();
    Random random = new Random();
    for (int i = 0; i < 8; i++) {
        char c = chars[random.nextInt(chars.length)];
        sb.append(c);   
    String name = sb.substring(0, 1).toUpperCase() + sb.substring(1);   
    driver.findElement(By.id("newName")).sendKeys("Cote" + name + name + name + "jay");
    driver.findElement(By.xpath("//*[@id=\"proposedNameForm\"]/div/div/div[1]/span/button")).click();
    driver.findElement(By.xpath("//textarea[@id='meaning']")).sendKeys("MEANING");

    Thread.sleep(900L);
    driver.findElement(By.xpath("//*[@id=\"nav-footer\"]/div/ul/li[1]/button")).click();
    driver.findElement(By.xpath("//button[@name='_target10']")).click();
    driver.findElement(By.xpath("//button[@name='_finish']")).click();
    driver.findElement(By.xpath("//a[contains(text(),'Return to Enquire Name Reservations')]")).click();
    Thread.sleep(900L);
    driver.quit();

Is that code provided by you is from a single method and you do not use loops? — Alexey R., Dec 03 '19 at 14:36
Hi Alexey, the code was provided from a single method. Do you know what the issue could be? Thanks — holla-holla, Dec 03 '19 at 15:56

The only issue I see in this code block is, you have switched to a frame only once:

driver.switchTo().frame("browsePeopleFrame");

Where as you have switched to defaultContent() twice as in:

driver.switchTo().defaultContent();
WebElement namingwait;
namingwait = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//ul[@id='categories-tabs']//a[contains(text(),'Naming')]")));
namingwait.click();
driver.switchTo().defaultContent();

You need to adjust your frame switching.

However, Selenium Java client v4.0.0-alpha-3 is a alpha release and shouldn't be used for Production Testing.

Additionally, ensure that:

ChromeDriver is updated to current ChromeDriver v79.0.3945.36 level.
Chrome is updated to current Chrome Version 79.0 level. (as per ChromeDriver v79.0 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.

Hi, thanks for your answer. So how do I fix the issue you mentioned about switching to frame once and defaultContent twice? – holla-holla Dec 03 '19 at 15:39
@holla-holla Yes, as you switched to frame only once, switching to default frame must be only once. – undetected Selenium Dec 03 '19 at 16:35
Hi, thanks for your reply again but how do I switch to default frame once when I need it to work for two codes? If possible, please help me amend the code. Thanks – holla-holla Dec 04 '19 at 08:16
@holla-holla Didn't get your point _...work for two codes..._, it is as simple as _...as you switched to frame only once, switching to default frame must be only once..._ – undetected Selenium Dec 04 '19 at 08:18
Hi DebanjanB, can you please help me rewrite the code as you explained as per the frame and default frame. Thanks – holla-holla Dec 04 '19 at 08:39

@holla-holla With out the relevant HTML it will be difficult to analyze and suggest exactly at which point you need to invoke `driver.switchTo().defaultContent();` But on a separate note, in the rarest of the rare cases you may need to invoke `driver.switchTo().defaultContent();` even when you have invoked `driver.switchTo().frame();` only once. I would suggest go for the trials removing one line of `driver.switchTo().frame("browsePeopleFrame");` at a time and look out if it works for either this or that. – undetected Selenium Dec 04 '19 at 15:21
