Yoast Sent Technical Issue Email

So my client forwarded a ‘Technical Issue’ email to me today that was flagging Yoast as the culprit. I was working on the site as it goes and had updated Yoast to version 26.8 before the email arrived. I was able to keep working on the site and didn’t see any ‘Critical Error’. Nonetheless I though I’d post the issue here and see what the response is.

WordPress version 6.9
Active theme: Themify Ultra Child (version )
Current plugin:  (version )
PHP version 8.1.34
