Bug: searching in posts shows white page

After plugin update the search function in wordpress backend under posts did not work anymore.
This comes with GET-parameter “apt_is_image”.
Instead of results page it only gets a blank site.

After deactivating these rows it worked again:

#add_action( 'restrict_manage_posts', [ $this, 'add_posts_filters' ] );
#add_action( 'pre_get_posts', [ $this, 'posts_filter' ], 10, 1 );
