Hamburger menu not opening on Homepage , other pages it works

I am a begineer and cant seem to make the Hamburger menu open on my home page (phone), the other pages it opens .

In the preview it opens but only half the contents can be seen , But when published on phone it never seems to work . When i click it just moves up and down but doesn’t open. I tried doing everything mentioned in the other queries like Positioning to fixed , z index etc … … Pls help . I just want the hamburger menu to open on my home page . PS . when i check it on inspect after publishing , it doesn’t open but dont know how to rectify it
