Im unable to login to my wordpress

This morning i tried login but facing issue stating that – There has been a critical error on your website. Please check your site admin email inbox for instructions.

But when i checked my inbox I dint find any mail from wordpress.

And when i checked the error log i found this issue : Call to undefined function wp_unregister_GLOBALS() in /home/de2awyowrkup/public_html/wp-settings.php:70
