Can't select dropdown value using Selenium

Question

I'm trying to select one of the dropdown values, using this code, but nothing happens:

selectopt = Select(driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-bc-reservation/div/div[1]/div[1]/select'))
selectopt.select_by_value('1cfc3cd0ac77bba30ffac794183100dc220758511a6c943264f8273d90eb54c2')

Also tried select by:

select_by_visible_text
select_by_index

Nothing happens :(

Update:

Adding full code, with slight change, still the same problem.

Code directs you to the page, does some actions, and at the last page, I need this bot to select item from drop down list, but I'am unable to do it.

Answer 1

All it needed was explicit waits.

try this instead :

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.select import Select

driver = webdriver.Chrome()
driver.maximize_window()
driver.implicitly_wait(30)
driver.get("https://eregitra.lt/advance-reservation/service")
wait = WebDriverWait(driver, 10)

vehicRegBut = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-service/div/div/div/button[1]')
vehicRegBut.click()

OneVehicRegBut = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-service/div/div/div[1]/button')
OneVehicRegBut.click()

NatPersonBut = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div/div[1]/button[1]')
NatPersonBut.click()

Name = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div[1]/div[1]/input')
Name.send_keys('Name')

SurName = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div[1]/div[2]/input')
SurName.send_keys('Surname')

Email = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div[1]/div[3]/input')
Email.send_keys('random@gmail.com')

Tel = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div[1]/div[4]/div/input')
Tel.send_keys('65555560')

CheckBox = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div[2]/div[1]/p-checkbox/input')
CheckBox.click()

NextBut = driver.find_element_by_xpath('/html/body/app-root/html/body/div/div/div[2]/div/div/app-details/div/div[3]/div[2]/button')
NextBut.click()

select_ = wait.until(EC.visibility_of_element_located((By.XPATH, "//select[contains(@class, 'select-text smaller-text')]")))
selectopt = Select(select_)
selectopt.select_by_value('1cfc3cd0ac77bba30ffac794183100dc220758511a6c943264f8273d90eb54c2')
