Have you run composer install or composer update on the hosting server? Do you have shell access to the hosting server? If you do, run the both the above compose commands (if everything is installed) or composer dump-autoload to rebuild all your class resolving.
I found the cause of the error. For security reasons, some hosting providers or managers like aaPanel disable the PHP readlink function on their machines. So the solution is you need to find a way to enable it again.
