FIX hamburguer-menu - does not trigger on certain page but does on others

Hello, I need someone to tell me why this hamburguer menu doe snot trigger on a certain page ( where it may be a conflict of .js ). this is the page [login to view URL] where the menu ( at the top left corner ) does not work. But if you go to homepage [login to view URL] it works perfectly. Can you tell me why doesn´t work without accessing the files ? note: I use two different bootstrap calls but I don´t think that is the problem: on the page I have problems: <script src="{{ '[login to view URL]' | asset_url }}" defer="defer"></script> on the rest: <script src="{{ '[login to view URL]' | asset_url }}"></script>
