Unable to save, edit and open the pages in WordPress

I am getting this below error while editing and creating new pages and save Updating failed. Error message: The response is not a valid JSON response.

Also when I am trying to open already created pages through user-interface, the addressbar showing the actual url of the page but that page is not opening it throw back to homepage but the addressbar showing the actual page url

and I try these things to solved the problem but nothing is happening: I try to disable the themes and also disbale all the plugin but nothing is happening I also try to recreate the .htaccess, activating new themes also not happening anythings.

I also check in the console of the browser there it is showing the below error: The response is not a valid JSON response.
