Revslider Deprecated after php update

Hi Heba, i was forced by my webserver hoster to update the php version to 7.2

Now i get a whitescreen in the Admin backend. Debugmode on. I deactivated Revslider and get these Informations.

What can i do?

Deprecated: Function create_function() is deprecated in /wp-content/plugins/revslider/includes/framework/functions-wordpress.class.php on line 257

Kind regards
