 > Hi @vjik. Having trouble recreating this issue. Are you still seeing it
 in the latest WordPress 5.6 beta? Does it happen when inserting a gallery
 into the post editor while using the Classic Editor plugin?

 Hello! In WP5.6 visually, everything works. But in console has error:

 {{{
 media-views.min.js?ver=5.6-beta3-49536:2 Uncaught TypeError: Cannot read
 property 'args' of undefined
     at i.<anonymous> (media-views.min.js?ver=5.6-beta3-49536:2)
     at f (underscore.min.js?ver=1.8.3:2)
 }}}
