Nav menu won’t open all of a sudden BUG!

Some please help before I break my phone lol. I have been working like a mad man on my site only for our or NO WHERE my nav bar menu button will NOT open my nav menu. Before I could open and close it very easily with just one touch or click. Now it takes at least two attempts and also I have have to wait to try it again.

Just to reiterate it will open but only after a little work and finessing. I changed absolutely nothing. Please help. With how long it took me to build and customize this nav bar I can’t completely start from scratch.
