Stuttering animations


i am having trouble with my scroll animations.
I have a Projekt for a client and i have a timeline to demontrate the process of working together.
The problem are the scroll animations. I have a 50% Offset on those animations. And a Lot of them.
I also have a Scroll animation that doesnt have an Offset and it also stutters. I dont know why.
Maybe it is alot of Lottie animations or to many animations or the bezier used to smooth the in and out of those animations.

Thanks in advance. I hope you have a lovely day.

Here is my public share link:

I found the Problem. The problem was a to complex lottie animation wich was 2.2 MB and had way to pany paths.
