[ErrorException]

The error comes from the line 83 in the file AbstractConfigurator from the symfony/flex repo when the gitignore is being configured because the .gitignore file does not exist yet.

    protected function updateData(string $file, string $data): bool
    {
        $pieces = explode("\n", trim($data));
        $startMark = trim(reset($pieces));
        $endMark = trim(end($pieces));
        $contents = file_get_contents($file);    // <---- here
        if (false === strpos($contents, $startMark) || false === strpos($contents, $endMark)) {
            return false;
        }
        $pattern = '/'.preg_quote($startMark, '/').'.*?'.preg_quote($endMark, '/').'/s';
        $newContents = preg_replace($pattern, trim($data), $contents);
        file_put_contents($file, $newContents);
        return true;
    }

Changing the line 83 to $contents = @file_get_contents($file); suppresses the exception and allows the installation to complete.
