Vue app.js colliding with other JavaScript files on homepage (Laravel)

I included Vuejs in my existing project but now it is affecting my original theme JavaScript files. Without app.js on my homepage, everything works fine. But when I include it, All UI effects and functionalities on my original theme js file including sliders, canvas, carousels, and dropdowns all stops working.

How do I stop Vue from colliding with my theme js and causing it to break
