Change header logo link

Hello @nvlctur
Go to function.php of child theme and add following function

if ( !function_exists( 'chld_thm_cfg_parent_css' ) ):
	function real_estater_child_custom_logo() {
	    $custom_logo_id = get_theme_mod( 'custom_logo' );
	    $html = sprintf( '<a href="%1$s" class="custom-logo-link" rel="home" itemprop="url">%2$s</a>',
	            esc_url( 'www.google.com' ),
	            wp_get_attachment_image( $custom_logo_id, 'full', false, array(
	                'class'    => 'custom-logo',
	            ) )
	        );
	    return $html;   
	}
endif;
add_filter( 'get_custom_logo', 'real_estater_child_custom_logo' );

Replace http://www.google.com with the required URL of your page.
To create a child theme you can use Child Theme Generator Plugin or go through the handbook https://developer.ww.wp.xz.cn/themes/advanced-topics/child-themes/

Thanks

Hello @nvlctur
You can try with this code

if ( !function_exists( 'real_estater_child_custom_logo' ) ):
	function real_estater_child_custom_logo() {
	    $custom_logo_id = get_theme_mod( 'custom_logo' );
	    $html = sprintf( '<a href="%1$s" class="custom-logo-link" rel="home" itemprop="url">%2$s</a>',
	            esc_url( 'www.google.com' ),
	            wp_get_attachment_image( $custom_logo_id, 'full', false, array(
	                'class'    => 'custom-logo',
	            ) )
	        );
	    return $html;   
	}
endif;
add_filter( 'get_custom_logo', 'real_estater_child_custom_logo' );

The code previously not copied exactly. I can see there is empty space https://prnt.sc/ui0zom making some issue.

So, please try with the above and if not fixed, then contact us through email.
