Sale Order email CSS inlining error

[Binod Yadav]

Hello Support Team,

I am facing issues CSS inlining error on Sale Order email template.

CSS inlining error: DOMXPath::query(): Invalid expression in selector /vendor/pelago/emogrifier/src/Emogrifier.php on line 502

Magento version  2.3.1
PHP Version  7.2.24

Can you please support on it.
 Is there any Server configuration issues or pelago/emogrifier version?
NOTE - I have loaded new sales order template from admin, but facing same issues.
