Gsap scrolltriger does not work with Bootstrap

I am using vue3, bootstrap 5, and gsap.

I put cdn in my code and applied bootstrap.

However, gsap’s scroll trigger does not work properly.

It works well if I remove start from scrollrigger.create or bootstrap cdn from index.html

If I comment like this, the scroll trigger works well

ScrollTrigger.create({
    // start: '10%',
    end: '100%',
    onUpdate: (self) => {
      self.direction === -1 ? showGoTop.play() : showGoTop.reverse()
    }
  })

or

If the annotation is removed, it does not work again.

After applying the bootstrap, the scroll trigger did not work.

What’s wrong with gsap’s start and end?
