Recommended action: Close any Chrome using that profile (including zombie test browsers), use a dedicated copy of the profile per session, or omit --user-data-dir so ChromeDriver creates a temp profile.
Option: Close any Chrome using that profile (including zombie test browsers), use a dedicated copy of the profile per session, or omit --user-data-dir so ChromeDriver creates a temp profile. [evidence: official_recommended_action]
Applies when: Starting a ChromeDriver/Selenium session with --user-data-dir pointing at a profile that a running Chrome (manual or leftover test browser) still uses
Steps:
1. pkill -f 'user-data-dir=<dir>' (or close Chrome).
2. Give each parallel session its own user-data-dir.
3. Check file permissions of <dir>/DevToolsActivePort.
Expected: The error no longer appears.
