@freerossagora Do you see the success message when you submit the form with Firefox etc?
I just tried with Firefox and as far as I could tell, everything worked successfully.
Presuming that your form is in the same location as this previous thread.
(But I obviously cannot see if you received the submission in your Netlify UI.)
The solution for this thread is specific to having used a honeypot field:

If you aren’t using that feature, then it won’t apply to you.
