SQLSTATE[HY000]: General error: 2006 MySQL server has gone away

Like the error says your server is not having enough resources to run the needed queries and your mysql server is throwing errors.
You need to improve the mysql settings like explained here: https://www.mailwizz.com/kb/mysql-mariadb-optimisations/

Also that log is not related to the campaigns sending, but with the queue processing.
