AttributeError: 'NoneType' object has no attribute 'suppress' using selenium webdriver

I am trying to scrape some links from https://www.mckinsey.com/capabilities/operations/our-insights using selenium with python.

Selenium webdriver: How to delete/flag spam comments on YouTube platform (without API)

I've been trying to flag/report a list of spam comments in a particular YouTube video.
For that I've been using this code on Python, which loads my previous profile so I log in with my account:
URL = "https://www.youtube.com/watch?
v=dvecqwfU6xw&lc=Ugxw_nsUNUor9AUEBGp4AaABAg.9fDfvkgiqtW9fDkE2r6Blm"
soup = BeautifulSoup(requests.get(URL).content, "html.parser")
options = webdriver.ChromeOptions()
user = pathlib.Path().home()
print(user)
options.add_argument(f"user-data-dir={user}/AppData/Local/Google/Chrome/User Data/")
driver= webdriver.Chrome('chromedriver.exe',chrome_options=options)
driver.get(URL)
wait=WebDriverWait(driver, 100)
comment_box = '//*[#id="comment"]'
reply_box ='//*[#id="replies"]'
while(True):
driver.execute_script("window.scrollBy(0, 200);")
try:
reply_box = driver.find_element(By.XPATH, reply_box)
print(reply_box.text)

# print(resp.text)
button = wait.until(EC.presence_of_element_located((By.XPATH,'//*[#id="button"]')))
driver.execute_script("arguments[0].click();", button)
The problem comes with opening the menu, I believe since you have to hover over the 3 dots menu it would then appear as the clickable menu so I never get to open the actual menu to report/flag the comment.
My mistake was not to take full Xpath path.... It works perfectly like this, THANKS

Selenium Selector is not consistent returning all options sometimes and other times not?

I apologize ahead of time for the length of this question but I want to give enough context.
I've been running in circles trying to figure out why this is happening. I'm indexing all the dropdown values of a bookstore and have done so successfully for 'departments' and 'course_nums' but when I try to do the same thing for 'sections' relative to the 'course_nums' it returns some of the lists of sections and fails to return others. I've seen alternative methods of getting options from Selector on Stack and Documentation but I've had no success with these methods.
When a dropdown is selected the attributes of the HTML get an additional id called
<option value="001" data-select2-id="703">001</option>
So I've tried to just use Selector without first clicking on the dropdown (by commenting out the DriverWait before the Selector in fill_sections()) but this does not work although the element is present in the DOM.
When run, it will sometimes return the corresponding course sections and other times an empty list of sections, but each course number should have at least 1 section. As I reviewed the automated input it's as if it goes too fast on some course numbers which might cause it to miss fetching all options, but I'm not sure. I'm stumped because this works for every other fetch for the departments and course numbers relative to the department.
Fair warning, let it run until it prints the arrays otherwise it starts this infinite loop for some reason when you hit
control-c and I honestly don't know why.
Upon request from the comments, here is the entire script relevant to indexing the departments, course_nums, and sections...

I run your code and usually problem was to fast running code - and it needed time.sleep() in some places - especially after sending ENTER (it used 1 second because 0.5 second was too small)
I put full code because I organized code in different way (I use nested for-loops`) and I used different XPATH (I tried to make them shorter and similar with different functions).
I also put all function at the beginning and put in order of use in main()
I also don't use global list departaments but I return list from function and assign to local variable. And later I do the same with courses and sections.

Code works perfectly fine sometimes,but sometimes i get the error:
Please note i am new at this,so an explanation would be very appreciated.I just learned how to use selenium and the reason i transitioned from beautifulsoup because of the lack of wait possibility,and now when trying to use that,i get this error SOMETIMES
See this :
driver = webdriver.Chrome(Path)
and how have you used it here :
try:
main = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.ID, "main-container"))
)
print("Page loaded,main retrived succesfully")
If you pay attention you would see that, you are using WebDriverWait(driver, 10) and passing driver reference.
But here
raw_name = WebDriverWait(product, 10).until(
EC.presence_of_element_located((By.CSS_SELECTOR, "h2.card-body.product-title-zone"))
).text
you are passing product in WebDriverWait, which is wrong, you should pass driver reference here. like
raw_name = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.CSS_SELECTOR, "h2.card-body.product-title-zone"))
).text
This should help you past this issue for sure.
also, make changes here
raw_price = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.CLASS_NAME, "product-new-price"))
)
