Selenium: This version of ChromeDriver only supports Chrome version N

ChromeDriver and Chrome must share the same major version. This message means the driver Selenium launched was built for one major version (the number after only supports Chrome version) and the browser it found is another (Current browser version is). The session is refused before any page opens.

It usually appears after Chrome auto-updates while an old chromedriver binary stays behind: one checked into a repository, installed by a package manager, sitting earlier on PATH, or passed explicitly through Service(executable_path=...). Since Selenium 4.6, Selenium Manager can download the matching driver automatically, but only when you do not override it with your own path or an outdated driver on PATH.

What is not wrong: your test code. Any script fails the same way until versions match.

# Selenium 4.6+: no driver path needed; Selenium Manager matches the driver
from selenium import webdriver

options = webdriver.ChromeOptions()
# Optional: pin a Chrome for Testing version for reproducible CI
# options.browser_version = "131"
driver = webdriver.Chrome(options=options)
print(driver.capabilities["browserVersion"],
      driver.capabilities["chrome"]["chromedriverVersion"])
driver.quit()

Let Selenium Manager handle drivers and keep the Selenium package current. Never commit driver binaries to a repository. In CI, pin the browser version explicitly so browser and driver change together, and add a smoke test that starts and quits a session before the real suite runs.
