I tried to update webdriver and browser to latest and check path is correct.

Your test worked fine in my environment, Windows 10, Python 3.12.2: C:\>chromedriver --version ChromeDriver 137.0.7151.70 (dfa4dc56b2abb56eb2a14cad006ea5e68c60d5de-refs/branch-heads/7151@{#1875}) C:\GitHub\RIDE>pip show robotframework Name: robotframework Version: 7.3 C:\>pip show robotframework-seleniumlibrary Name: robotframework-seleniumlibrary Version: 6.7.1 — Helio

if no port is set the driver will try to read the file the browser drops when in dev-mode. That file includes the port and sessionID for wire protocol. It's possible it was reading an old file from a previous session. (if that session crashed and didn't cleanup) I forgot the directory it drops the file in but I believe it is per user. — browsermator

As original author of webdrivermanager - the tool is not updated anymore and selenium ships with Selenium Manager that provides the same functionality if you are on new enough selenium version. selenium.dev/documentation/selenium_manager
