Nu Html Checker

Hello –

I am confused.

In 2018 I had checked this page as valid HTML5.

Today, not so much.

I made a noted change from <html> to <html lang="en”>, that killed one warning.
It also told me I did not need type attribute for style element
 and also same for JavaScript resources ( on 2 lines )
Those were fine.

But also the Nu Checker keeps reporting 2 errors in line 56, in code that is not even on my web page.

My line 56 is –
 </body>
Nu Checker line 56 is –
 <!-- Start McAfeeSecure Code --><script type="text/javascript" src="//cdn.ywxi.net/js/1.js" async="true"></script><!-- End McAfeeSecure Code --></BODY>↩

which throws this ERROR and warning – 
Error: Bad value true for attribute async on element script <https://html.spec.whatwg.org/multipage/#the-script-element>.
From line 56, column 33; to line 56, column 105 <https://validator.w3.org/nu/?doc=https%3A%2F%2Fcellier.org%2Fbrownianmotion.org%2Findex.html&showsource=yes#l56c105>
e Code --><script type="text/javascript" src="//cdn.ywxi.net/js/1.js" async="true"></scri

Help?
