Contact Form 7

Good morning,
I am using Contact Form version 5.7.7 under WordPress 6.2.2 with the Blossom Spa Pro and Elementor theme.
When I want to modify some pages including your [contact-form-7 id=”nnn” shortcode, I get an error.
I have to disable the plugin to be able to edit the page.
Can you help me ?
Here is the copy of the error message:

TypeError: Cannot read properties of undefined (reading ‘indexOf’) at n (https://visitfosses.be/wp-includes/js/dist/editor.min.js?ver=1fb5fcf129627da4939e:19:106536) at https://visitfosses.be/wp-includes/js/dist/editor.min.js?ver=1fb5fcf129627da4939e:19:106654 at Array.sort() at https://visitfosses.be/wp-includes/js/dist/editor.min.js?ver=1fb5fcf129627da4939e:19:106632 at https://visitfosses.be/wp-includes/js/dist/editor.min.js?ver=1fb5fcf129627da4939e:19:106705 at Object.qt as useMemo at e.useMemo (https://visitfosses.be/wp-includes/js/dist/vendor/react.min.js?ver=18.2.0:10:9875) at Vi (https://visitfosses.be/wp-includes/js/dist/editor.min.js?ver=1fb5fcf129627da4939e:19:106498) at kt (https://visitfosses.be/wp-includes/js/dist/vendor/react-dom.min.js?ver=18.2.0:10:47633) at gr (https://visitfosses.be/wp-includes/js/dist/vendor/react-dom.min.js?ver=18.2.0:10:56448)

Also, this only happens if I choose the “French” language. It’s ok with English (UK)
