Cannot send form after disabling hcaptcha

Hi Vyacheslav,

after disabling the hCaptcha Spam Protection Integration I cannot send my form.

I see this in the Chrome console.log:

```
ba-form.js?2.4.3.3:3323 Uncaught (in promise) TypeError: Cannot read properties of null (reading 'invisible')
at FormsHCaptcha.getResponse (ba-form.js?2.4.3.3:3323:28)
at CaptchaHelper.isValidResponse (ba-form.js?2.4.3.3:3436:40)
at CaptchaHelper.checkResponse (ba-form.js?2.4.3.3:3447:43)
at HTMLAnchorElement. (ba-form.js?2.4.3.3:1922:51)
at HTMLAnchorElement.dispatch (jquery.min.js:2:40035)
at v.handle (jquery.min.js:2:38006)
````
Any ideas?
Kind regards,
Bernhard
