Exhausting Memory!

It sounds like you may have a plugin – or perhaps several plugins – taking up more memory than they should. Assuming your memory limit is at least 128mb (see here for more info https://wpsso.com/docs/plugins/wpsso/faqs/how-can-i-fix-a-php-fatal-out-of-memory-error/), then you may have one or more third party plugin filters that are being run by WPSSO and WordPress that exhaust the available memory. I would suggest using the Query Monitor plugin to see which plugins are taking more memory than they should (comparatively). See here for more info: https://wpsso.com/docs/plugins/wpsso/installation/troubleshooting-guide/

One a standard system using the default WPSSO settings, WPSSO uses very little memory. See here for more info: https://surniaulula.com/2021/apps/wordpress/plugins/wordpress-seo-plugin-performance-report-for-q4-2021/
