[Violation] 'requestIdleCallback' handler

Hi ! how are you ? I am trying to use form.php with captcha, and in my console I get the following when i click submit:

[Violation] 'requestIdleCallback' handler took 131ms

after that i get a Captcha not validated ! in my error alert uop the toop corner.

In my contact.php page I have a form with this:

<div class="col-12 form-group">
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
<div class="g-recaptcha" data-sitekey="6LdzQzIbAAAAACZT27ny_8apoArwxze_GW0FnTQ2"></div>
</div>

in my form.php (under include folder). I have:
-------------------------------------------------
reCaptcha
---------------------------------------------------/
// Add this only if you use reCaptcha with your Contact Forms
$recaptcha_secret = '6LdzQzIbAAAAACZT27ny_8apoArwxze_GW0FnTQ2'; // Your reCaptcha Secret

I don´t know if I miss something, thanks a lot for your replay !!

I follow the steps in the canvas documentation, there is a link to create the reCaptcha in google
The link provided is : https://www.google.com/recaptcha/about/

there is not optioon at this moment to choose what kind of version you would like to work with.
Any suggestion I guess is v3 right now
thanks a lot.
