PHP warning in WP error log

[louptn]

Getting a recurring warning:
PHP Warning: count(): Parameter must be an array or an object that implements Countable in /public_html/wp-content/plugins/coursepress/2.0/include/coursepress/data/class-course.php on line 1635
PHP Warning: count(): Parameter must be an array or an object that implements Countable in /public_html/wp-content/plugins/coursepress/2.0/include/coursepress/data/class-course.php on line 1637

Relevant lines are the same code:
$part = count( (array)$components > 0 ) ? array_pop( $components ) : 0;

Tried a fix along the lines of:
$part = (array)$components && count( (array)$components > 0 ) ? array_pop( $components ) : 0;

But still having the warning...any thoughts?

Running on WP 5.6 and PHP 7.3.23 (I am running it for a free workbook that can be signed into and worked on and saved, so i have not had to edit courses and don't dare go in there to see if i even could :-) just basically let it be while it works)
