/app/src/Legacy/G/DB.php:56 Not Found

[user_f617b]

For a while I couldn't run the cron automatically because of this error so I've just been running it manually but now I cannot update to 4.2.0 because of the same error so I wondered what is causing this because the file does exist.
The server is Ubuntu 22.04 with WHM/cPanel. File and folder permissions are set to user:user

• Database server offline.
