Hey there, thanks for reporting this issue.

We'll need more info and/or code to debug this further. Can you please create a repository with the command below, commit the code that reproduces the issue as one separate commit on the main/master branch and share the repository here?

Please make sure that you have the latest version of the Laravel installer in order to run this command. Please also make sure you have both Git & the GitHub CLI tool properly set up.

laravel new bug-report --github="--public"

Do not amend and create a separate commit with your custom changes. After you've posted the repository, we'll try to reproduce the issue.

Thanks!

No matter how uniquely I regenerate --user-data-dir, I keep encountering an error saying "already in use" when making a POST request to http://localhost:9515/session.

chromedriver version : ChromeDriver 132.0.6834.84 (c1a6c2d428b5b484febdecda9475aba38de5a502-refs/branch-heads/6834@{#3391})
chrome version : Google Chrome 132.0.6834.84

When I run dusk:chrome-driver --detect, it installs version 83, and even after updating to the latest version, the issue persists.

but The same source works fine when run on another Mac machine.

Can you try using Chrome for Testing: https://developer.chrome.com/blog/chrome-for-testing

It would be impossible to solve this without a reliable way to replicate the issue.
