$session->destroy() throws exception

Oh, I got your problem!
It is your miscoding.
You cannot destroy uninitialized session.
PHP causes an error (Warning), and CI4 make all errors into Exceptions.

If you want to destroy Session, you must start the session.

PHP Code:

        $session = \Config\Services::session();
        $session->destroy();

        $session->start();
        $session->destroy();
