Critical Error on form submission

My client informed me this morning that the websites Yith RAQ form wasn’t submitting, and instead goes to a blank page with critical error message ” There has been a critical error on this website.” I have now activated the debug report and got this:

Parse error: syntax error, unexpected ‘}’, expecting end of file in /home/customer/www/wiredisplays.co.nz/public_html/wp-content/themes/Divi-Child/woocommerce/emails/plain/request-quote.php on line 60

There has been a critical error on this website.

I am not familiar with php coding, but on putting this log into chat gpt it said i needed to remove that bracket and make sure that the various brackets were matching. It is in relation to me adding a plain email template (client needed this), but there appears to be something fishy with it! (oddly, it has been in place for 3 weeks and only caused critical error yesterday). I’ve removed the bracket on line 60, and now the form sends correctly – but now I’m not receiving it in my inbox! (as test). I’ve tested the smtp server (wpmail and brevo), and its working, it sends the test email. I’m a bit stumped. Here is the php code if anyone has a clue it would be appreciated?!

code

	exit; // Exit if accessed directly.
}
