Upgrading Drupal

I am getting 2 errors preventing me from doing basic tasks. I searched and read about these, I understood that this is a deprecation mismatch.

During update.php:

Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "entity.manager". in Symfony\Component\DependencyInjection\ContainerBuilder->getDefinition() (line 1030 of /var/www/html/vendor/symfony/dependency-injection/ContainerBuilder.php).

On many admin pages WSOD:

I'm trying to upgrade an existing Drupal site and when I upgrade Geolocation Field from 8.x-1.11  to 8.x-3.7 I break my location searching and start getting the error of a non-existent service "geolocation.core".  I have not been able to find any documentation on how to update my php call...

I am currently running Drupal 8.9.18 and am upgrading local development site to D9. I have upgraded all modules and the upgrade_status module tells me all is well. I now need to upgrade the platform for PHP and MariaDB. I have successfully installed a new lamp stack from BITNAMI version 8.1.4-0, and created and restored database from backup

DB is Server version: 10.4.24-MariaDB - MariaDB Server

PHP is Version 8.1.4

Apache 2.4.53

Title is the short story.

Problem is a bit longer than that. The problem is, I upraded in January, and it works fine so I thought nothing of it. That is, until the browser autoamtically logged me out. And now I can't access the site via login to admin.

Short of revveting to January, is there a way to force the login or others are familiar with getting around this issue? What bugs me most is that I thought there was no problem after all this while until I was logged out.

Hi all,
