The side menu drop-down button on my phone is not working. /Dj-MegaMenu/top-menu-nav

Hello,
The side menu drop-down button on my phone is not working. On the computer works but it's a different module as if.

What could be the reason why the menu doesn't appear on my phone when you click?

Please help.
