WordPress 5.6 issue

Good evening,
I want to report a problem that I found with your plugin: today I updated my site from the version of Wprdpress 5.5.3 to the version 5.6 released yesterday.
Once the update is done, every time I go to click the mouse somewhere on the site, a black overlay appears to me as big as the whole site like the one in the gallery, but it does not close. If I go to refresh the web page, it disappears, and then reappears by clicking anywhere on the site.
I checked from the inspector and the problem appears to be one of your plugin files.
Could you please help me?

I can try to help you by providing the following data (at least what I seem to see):
– the overlay appears in the body with the following line of code:
<div id = "swipebox-overlay" style = "width: 2560px; height: 781px;">
– the file that makes the overlay appear could have the following path:
… / plugins / responsive-lightbox / assets / swipebox / swipebox.min.css

Thank you for your availability,
I await feedback.
