Problem after update

Hello
Following the update to Joomla 4.2.2 and SP Page builder 4.0.4.
My site is completely broken
The links no longer work.
The pages are not displayed.
The error seems to be:
Object of class stdClass could not be converted to string
Moreover, from the admin page buider, if I copy the link of a page, I get an error message.
Only one page works, the one reserved for the super user, and here all the links to the articles
This situation is really very penalizing for me.
I really need help
