All In One SEO working great for me again, likely a combination of going through their settings (many changes in recent updates) … but most likely solved with PHP 7.3 (should work for 7.4 too) to increase limits, giving more resources to WordPress – in cPanel update ‘MultiPHP INI Editor’ which updates .htaccess file with the following which works for me, might might work for you too:
# BEGIN cPanel-generated php ini directives, do not edit
# Manual editing of this file may result in unexpected behavior.
# To make changes to this file, use the cPanel MultiPHP INI Editor (Home >> Software >> MultiPHP INI Editor)
# For more information, read our documentation (https://go.cpanel.net/EA4ModifyINI)
