Many PHP bugs – unusable

I loaded the latest version on a site to evaluate this plugin. I have many custom post types. The basic settings screen lets me pick post types, but I have this displayed on it.

Notice: Undefined property: stdClass::$apvc_spam_controller in /var/www/html/lsnwp/public/wp-content/plugins/advanced-page-visit-counter/admin/class-advanced-page-visit-counter-admin.php on line 2757

Notice: Trying to access array offset on value of type null in /var/www/html/lsnwp/public/wp-content/plugins/advanced-page-visit-counter/admin/class-advanced-page-visit-counter-admin.php on line 2757

On the front-end of the site when viewing an article, there are these errors:

Notice: Trying to access array offset on value of type null in /var/www/html/lsnwp/public/wp-content/plugins/advanced-page-visit-counter/public/class-advanced-page-visit-counter-public.php on line 246

Notice: Undefined property: stdClass::$ip_anonymize in /var/www/html/lsnwp/public/wp-content/plugins/advanced-page-visit-counter/public/class-advanced-page-visit-counter-public.php on line 247

Notice: Trying to access array offset on value of type null in /var/www/html/lsnwp/public/wp-content/plugins/advanced-page-visit-counter/public/class-advanced-page-visit-counter-public.php on line 247

Notice: Uninitialized string offset: 0 in /var/www/html/lsnwp/public/wp-content/plugins/advanced-page-visit-counter/public/class-advanced-page-visit-counter-public.php on line 286

So many glaring bugs, this plugin is not production ready.
