edit interface failing with out of memory error

Where a slider is added to a page in WordPress 6.6.2 and the following options are selected design=’design-2′ through ‘design-5’ and the show_contents option is unset or set to ‘true’ once the page has been saved, on attempting to access the edit interface for that page (using the gutenberg editor) there is a fatal error PHP message: PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 16384 bytes) in /var/www/html/wp-content/plugins/wp-slick-slider-and-image-carousel/includes/shortcodes/wpsisac-slider.php on line 112

on investigation this error can be resolved by using <?php echo get_the_content() ?> rather than <?php the_content() ?> in the affected templates (see patch file below)
