Comment:

 I can't reproduce this with a default theme and no plugins enabled using
 the following test code on php 7.3.2
 {{{#!php
 <?php
 add_action( 'wp_head', function(){
         get_the_excerpt();
 });
 }}}

 It sounds like a plugin or theme is overriding the $pages global and
 setting it to the wrong object type.
