The browser starts up, but it doesn't work and times out, closes, and gives the above error. Please let me know how to solve this.

Getting the same issue with Chrome >= 128 when A) running PHP for Windows in B) SAPI mode (e.g. Apache). In the logs, everything looks good (in my use case, I successfully invoke Page.printToPDF and see that DevTools logs "firstMeaningfulPaintCandidate"), except Chrome never writes a response to the web socket.

A workaround for me was disabling sandbox mode, e.g.:

$browserFactory->createBrowser(['headless' => true, 'noSandbox' => true]);

This may have security implications, depending on what you're using Chrome for; these can be mitigated by running Chrome inside a container.

Thank you for answering! I tried it, but it didn't work. Is there any other way?

In my environment, that error occurred when CPU resources were insufficient.
I think too long time to process

Chrome was updated on our production server yesterday eve to 128.0.6613.85. Now, chrome-php times out. Running on Windows IIS with php 8.2.20; tested with php 8.3.10 with same results.

Also experiencing this issue with Windows PHP 8.1 nts x64 and PHP 8.2 nts x64. Issue occurs using php-cgi.exe with IIS and php.exe from command line. Disabling sandbox mode has resolved the issue for now.
$browserFactory->createBrowser(['headless' => true, 'noSandbox' => true]);
