simple landing page on wp. Used only bootstrap4 and owl-carousel link to the site

Disconnected modules one by one, it still hangs, what could be the problem? because of the two roundabouts?
upd
As I understood the problem in two versions of the Yandex map. because there was no way to make two cards on the site in one version at once, I decided to make two cards with two different versions 2.1 and 2.0 and it hinders the campaign because of this, how to solve the problem? upd
The problem is not Yamapa

  • Try downloading js at the end of the page, not at the beginning - user192664
  • @NikitaSmith tried, no way - reddyk
  • I didn’t see how resources are loaded in the developer’s console (download time and order) - Yuri
  • Two or more cards can be placed with one Ya.kart script. Open another question if you want to learn how to do it. - Total Pusher
  • @TotalPusher as it turned out the problem is not in Yamapa - reddyk
