Fatal PHP error

Hello, and thank you for your plugin. It’s very helpful.

I have been getting the following PHP error every few days or so, and I would love to know what it’s about.

PHP Fatal error: Uncaught Error: Call to a member function set_loggers() on null in /home/XXX/public_html/wp-content/plugins/wp-optimize/vendor/team-updraft/common-libs/src/updraft-tasks/class-updraft-task-manager.php:334
