[Defender Pro] Error: wp-includestheme-compatembed.php:13

Working with the file PHP72x64_errors.log we are getting items added constantly by the line 13 error from wp-includestheme-compatembed.php:13.
From reading another post topic in the forum I see that this could be generated by Defender. In those and other posts I read where a line in .htaccess could be written to stop the errors from being logged.
We are on a Windows server so .htaccess does not work.
Does anyone know a way we can turn off these specific errors from writing to the file? Not all errors just these.
Thank you for your help.
