PHP Fatal error:  Uncaught TypeError: explode()

I’m getting this error on my site on a fairly regular basis:

PHP Fatal error:  Uncaught TypeError: explode(): Argument #2 ($string) must be of type string, array given in /xxx-hidden-xxx/wp-content/plugins/responsive-lightbox/includes/class-frontend.php:802

I’m not sure which page it’s happening on, but it looks like an Elementor page – yet all the ones I’ve looked at don’t seem to use a WP Media widget . like indicated in the stack. I’m wondering if anyone has seen this or has any idea how to resolve it. The full error chain is:
