[🐛 Bug]: Can't attach to Edge using remote-debugging-port

[la2ygoo]

Description

It was functioning normally yesterday, but it's not working this morning.
Even after updating both Edge and EdgeDriver to version 154.0.4258.53, selenium==4.50.0, seleniumbase==4.55.0, it's still not working

Reproducible Code

"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --remote-debugging-port=9222  

    from selenium import webdriver
    from selenium.webdriver.edge.options import Options
    options = Options()
    options.add_experimental_option("debuggerAddress", "127.0.0.1:9222")
    driver = webdriver.Edge(options=options)

"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --remote-debugging-port=9222

Starting with Chrome 136, --remote-debugging-port does not work when used with the default data directory: https://developer.chrome.com/blog/remote-debugging-port

(MS Edge also inherited this behavior)

If you launch Edge with --user-data-dir pointed to a different location, it should work.

try:

msedge.exe --user-data-dir="%TEMP%\edge-debug" --remote-debugging-port=9222

... then your code should be able to attach to it.

It's working perfectly now. Thank you very much
