Mobile Nav Menu Opens then Closes

First I was trying to remove the scroll bar from desktop view because it was moving my top navigation bar when switching between tabs/pages. I added some custom code and it fixed the problem, however it has opened another issue and now on mobile view the hamburger opens then closes suddenly. How to fix this issue? You must view the website on an actual mobile phone and not on preview because it only shows via mobile.

Update: I had to revert back to my old settings since it made such a huge mess.

This was the code I was using to remove the scroll bar on the page.

/* removing scroll bar(vertical) */ ::-webkit-scrollbar { display:none; }

How can I apply this code to remove the scroll bar but also prevent mobile menu from scrolling (opening / closing ) on me?

I think I fixed it! Thanks
