Form not submitted

After updating, my form stopped sending emails, and I can't find the reason.
After submitting the form, no message appears and the email does not arrive at the email addresses specified in the settings, although the message appears in Forms =>> Submissions
Email sending in Joomla is configured via SMTP and works - a test message arrives.
The following errors appear in Firefox Inspector:
