Learnpress crash

Hi,

I installed a new and up-to-date WP instance. Then I installed latest CorpTrain template which includes Learnpress, however Learnpress keeps crashing, even after I reinstalled it for a few times.

I noticed the similar issue was opened yesterday.

Fatal error: Uncaught Error: Call to a member function get() on null in /var/www/academy/wordpress/wp-content/plugins/learnpress/inc/custom-post-types/course.php:158 Stack trace: #0 /var/www/academy/wordpress/wp-includes/class-wp-hook.php(307): LP_Course_Post_Type->register_taxonomy() #1 /var/www/academy/wordpress/wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters() #2 /var/www/academy/wordpress/wp-includes/plugin.php(474): WP_Hook->do_action() #3 /var/www/academy/wordpress/wp-settings.php(587): do_action() #4 /var/www/academy/wordpress/wp-config.php(96): require_once('/var/www/academ...') #5 /var/www/academy/wordpress/wp-load.php(50): require_once('/var/www/academ...') #6 /var/www/academy/wordpress/wp-blog-header.php(13): require_once('/var/www/academ...') #7 /var/www/academy/wordpress/index.php(17): require('/var/www/academ...') #8 {main} thrown in /var/www/academy/wordpress/wp-content/plugins/learnpress/inc/custom-post-types/course.php on line 158
