Replaced Lottie in Website now whole website is acting up

So I was literally almost done with my website everything was working fine until I replaced my lottie animation and site started acting crazy. Now it won’t scroll properly it jitters on scroll my scrolling animations dont work at all now in Chrome this sucks. Can somebody help me and see maybe what i did wrong?! I do have some custom html before the body, but i haven’t changed that I didn’t change anything on my website just the lottie animation. Idk if its maybe because of my internet or RAM idk but now nothing is working I even restored backup from last night and its not working properly please help! Thank you.
