## Title

    Proposed fix: [ChromeDriver] 'session not created: Chrome instance exited. Examine ChromeDriver verbose log to determine the cause.' / 'unable to discover open pages' / 'Timed out while waiting for Ch

## Body

    Recommended action: Run chromedriver with --verbose --log-path and --enable-chrome-logs to see why Chrome exited; avoid args that make Chrome exit or open no window, don't pass remote-debugging-port manually, and increase the startup timeout on slow machines.
    
    Option: Run chromedriver with --verbose --log-path and --enable-chrome-logs to see why Chrome exited; avoid args that make Chrome exit or open no window, don't pass remote-debugging-port manually, and increase the startup timeout on slow machines. [evidence: official_recommended_action]
    Applies when: Starting Chrome through ChromeDriver where Chrome exits cleanly right away or never exposes a page target
    Steps:
    1. chromedriver --verbose --log-path=cd.log --enable-chrome-logs
    2. Remove custom --remote-debugging-port / conflicting args.
    3. Retry with a fresh temp profile.
    Expected: The error no longer appears.
