Fatal error: Uncaught Error: Class ‘WP_Block_Styles_Registry’


I am having some issues determining the solution to this problem below. The website was sent to our team to fix.

Turned on error reporting in wp-config.php:
define('WP_DEBUG', true);

WordPress version: 5.3.2
PHP version: 7.2

WordPress Theme: Grow Pro
