Conflict JSON | WordPress.org

Good morning,
I have a problem when I want to save an article in the backoffice. I get the error “Unable to update, the response is not a valid JSON response”. By disabling all modules and enabling them one by one, your plugin causes this error. How to correct this? I only use it for external links.

My Website Configuration : Template Jannah, Yoast SEO, Itheme Security, Cache Enabler…. WP 6.1.1 and PHP version 8.0
THANKS
Cordially
Nicholas
