I've also encountered similar problem

driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()))
driver.get('https://test.com/Login/')

Found the solution, just use this instead

driver = webdriver.Chrome()

rather than webdriver_manager. Seems selenium has now been able to auto update the driver

[cobaltautomationdev]

Automated driver management
TL;DR: Selenium Manager automatically discovers, downloads, and caches the drivers required by Selenium when these drivers are unavailable.

The primary feature of Selenium Manager is called automated driver management. Let’s consider an example to understand it. Suppose we want to driver Chrome with Selenium (see the doc about how to start a session with Selenium). Before the session begins, and when the driver is unavailable, Selenium Manager manages chromedriver for us. We use the term management for this feature (and not just download) since this process is broader and implies different steps:

Browser version discovery. Selenium Manager discovers the browser version (e.g., Chrome, Firefox, Edge) installed in the machine that executes Selenium. This step uses shell commands (e.g., google-chrome --version).
Driver version discovery. With the discovered browser version, the proper driver version is resolved. For this step, the online metadata/endpoints maintained by the browser vendors (e.g., chromedriver, geckodriver, or msedgedriver) are used.
Driver download. The driver URL is obtained with the resolved driver version; with that URL, the driver artifact is downloaded, uncompressed, and stored locally.
Driver cache. Uncompressed driver binaries are stored in a local cache folder (~/.cache/selenium). The next time the same driver is required, it will be used from there if the driver is already in the cache.
