Contact form not working anymore

Hi everyone,
sorry but I need some help…

Contact forms in the website don’t work anymore..

I upgraded the website to WP5 then I generated reCAPTCHA v3 and integrated all codes (recaptcha badge appears in all pages of the website).
I removed [recaptcha] shortcodes from all the modules…
email address didn’t changed. The only thing that changed from last week is the new english translation of the entire site (WPML)

I know there are several forms in the website but that’s needed…
Now every message isn’t sent… and appears the error message in red box…

Any suggestion?

Thank guys
Elisa
