Attempt to read property “post_type” on null

Hello!

I am using the latest version of Elementor and Tutor LMS. This is not a critical error, but my error_log keeps growing because of this.

The error is the following:

[22-Sep-2023 15:07:24 UTC] PHP Warning: Attempt to read property "post_type" on null in /home/user/domain.com/wp-content/plugins/tutor-lms-elementor-addons/classes/AddonsManager.php on line 43

By adding a null-safe operator (PHP 8+), the error disappears:

line 43:  if ( $post?->post_type && $post?->post_type == tutor()->course_post_type ) {}

But taking in mind the compatibility with PHP 7 or lower, the best thing would be:

line 43: if ( $post && $post->post_type && $post->post_type == tutor()->course_post_type ) {}
