Polylang – error 404

Hi,

I’m trying to translate a website using the Polylang plugin. I did the settings using the Wizard, but when I try to translate the individual pages it says Page Not Found (404), and Elementor can’t even start.

Polylang version 3.5.3

please urgently because I don’t see any solution on the forums, each one is temporary. And I see that it was said that it will be solved with new updates, but it is not. I get the same error on multiple installs, even on localhost.
