Critical error when publishing/saving drafts

[05-May-2022 17:27:36 UTC] PHP Fatal error:  Uncaught Error: Call to a member function getTOC() on null in /home/%USER/public_html/wp-content/plugins/easy-table-of-contents/easy-table-of-contents.php:609

So, this is the log basically. Seems like it is a conflict with link-whisper-premium?

I can publish/edit easily after disabling easy TOC.

Thanks!
