Hey @laraws could please tell the steps you did before running this? Are you using Docker? What output did composer install show?

It solved after I ran the composer update. It may be a format problem. I copied the project from the GCP Ubuntu instance before I did . /vendor/bin/phpcs. . I'm using docker with PHP environment.

Delete /vendor and composer.lock, and rerun composer install
