I found a fix for Ubuntu 18.04. I downgraded the package php-symfony-polyfill-apcu back to 1.6.0-2. Apparently, the version that was upgraded no longer includes all the same files, including the 'Symfony/Polyfill/Apcu/autoload.php' file, that is causing the issue here.

sudo apt install php-symfony-polyfill-apcu=1.6.0-2
sudo service apache2 restart
