Errors after installing Risen Hope template for J4

headcake

I don't believe the Shape 5 Risen Hope 1.0.6 template is Joomla 4-compatible. The website failed to load when that template is set to default. There are a lot of errors, it’s calling files that only exist in Joomla 3.
I installed the new template but it gives an error on the frontend. The template version is 1.0.6. When I switch to Joomla core template Cassiopeia there’s no problem. I haven’t been able to find a cause for the error. It goes to an error page instead of the site and that’s where the problem is reported:

headcake Hi

I updated this file: ROOT/templates/risen_hope/vertex/responsive/responsive_mobile_menu/sidebar_url.php

Line 89:

//$options = 'toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=yes,'.$params->get('window_open');
if (is_object($params)) {
	$options = 'toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=yes,' . $params->get('window_open');
}

Kindly check.
