Lightbox not working after update

After the update to wordpress 5.6 the lightbox is not working anymore.

We get this error in the console:
jquery.min.js?ver=3.5.1:2 Uncaught TypeError: Cannot read property ‘tagName’ of undefined
/wp-content/plugins/responsive-gallery-grid/lib/simplelightbox/simple-lightbox.min.js?ver=2.3.6

We use this shortcode:
[gallery ids='123,23423' margin='5' scale='1.1' maxrowheight='250' rowspan='0' intime='100' outtime='100' captions='title' linked_image_size='medium' link='file' size='thumbnail' lightbox='simplelightbox' effect='bubble' lastrowbehavior='last_row_same_height' captions_effect='slide_up' captions_intime='200' captions_outtime='200' rel='rgg' type='rgg']

Please help us out!
