CRITICAL Uncaught Error and stops at 10% when regenerating feed

To whom it may concern,

I have been using CTX FEED for sometime and it works great. However, it stopped generating feed and showed errors since 7 July until now, as you can see from the latest error log below:

2023-08-06T00:11:45+00:00 CRITICAL Uncaught Error: Call to undefined method WC_Privacy_Background_Process::maybe_wp_die() in /home/customer/www/berserkeys.com.au/public_html/wp-content/plugins/seo-by-rank-math/vendor/a5hleyrich/wp-background-processing/classes/wp-background-process.php:337

If I click the "View Feed" button, it simply shows the following error message:

This page contains the following errors:

If I click the "Regenerate" button, it will just stop at 10% and cannot proceed anymore. I have read the help doc and tried to fix the issue a few times but not successful.

Please kindly take a review and advise what caused this error and how I can resolve this issue. Thank you.

I look forward to hearing from you soon.

Kind regards,

Martin
