php parse error

Hi !
I have this error
Parse error: syntax error, unexpected token ")" in /home/mywork/vendor/codeigniter4/framework/system/Autoloader/Autoloader.php on line 165
because of the line
spl_autoload_register($this->loadClassmap(...), true);
I am running codeigniter 4.6.0 on php8.0.
I spent hours on this error and now I ask some help because I really have no idea how to fix it !!!
Someone a solution ?
Thanks in advance.

PHP is 8.0 is out of service Nov 2023, update your PHP Version to 8.1 or higher.

But you may have a misplaced ) somewhere in your code.

v4.6 requires PHP 8.1 or higher. Update your PHP version. The error is about first class callables which are available in PHP 8.1

Thanks guys it works !
