Hi!
So quick answer, thanks!

This problem occurs on several websites.

An example from a test website with the problem:

site: https://kaiturovagalina.heartweb.ru/

WordPress 5.5.1
php 7.2 (Python 3.4)
There is only one plugin installed on this website – WP Content Copy Protection (Lite).

An error message:
