The issue does not happen if we initiate the Behat test in a single thread. The issue only happens if we initiate the Behat test in parallel mode.

Steps to replicate

1. Make sure that your environment is using PHP 8.1
2. Execute command line: php admin/tool/behat/cli/init.php -j=2
3. Execute command line: php admin/tool/behat/cli/util.php --drop
4. Verify the output.
