Envira Gallery is not being disdplayed in Chrome and Firefos

Envira Gallery on this page https://anastasiatsapko.com/event/master-klass-fashion-portret in the middle part is not being displayed in Chrome and Firefox but is displayed in Safari. It’s working OK here https://anastasiatsapko.com/course/maslyanaya-zhivopis I have checked the console, looked at all the files I changed recently, turned off all plugins but nothing helped. I ran out of ideas what the problem can be. Please help me handle this.
