Proposed fix: [Puppeteer] 'The browser is already running for <userDataDir>. Use a different `userDataDir` or stop the running browser first.' vs 'The browser cannot write to <userDataDir>'
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Give each concurrent launch its own userDataDir; kill orphaned Chrome processes (and remove stale Singleton* files only after confirming none run); fix ownership/permissions of the profile dir.
Option: Give each concurrent launch its own userDataDir; kill orphaned Chrome processes (and remove stale Singleton* files only after confirming none run); fix ownership/permissions of the profile dir. [evidence: official_recommended_action]
Applies when: Launching with a fixed userDataDir (persistent profile), in parallel workers, after a crashed run, or with a read-only/root-owned profile dir
Steps:
1. pkill -f -- '--user-data-dir=<dir>' for orphaned processes.
2. Use per-worker userDataDir paths.
3. chown the profile dir to the running user.
Expected: The error no longer appears.
