ERROR emailprotector V 4.65 on the website

Hello
Okay?

I use Joomla 3.9.22 and php 7.3

I was updating emailprotector to version 4.65, and when opening our Home page, the following error started to appear in our home

Call to undefined method RegularLabs\Plugin\System\EmailProtector\Document::addHeadStuff()
It appears the page you were looking for doesn't exist. Sorry about that.

Then I disabled the email protector plugin and the page went live again without errors

Bo help me know why this occurs?

I look forward to your help
thank you very much
Health and success

Health and Success Always
