解决了问题。
对于那些可能需要更多的人，我会留下代码：）

const arrText_Slider = new Array('text','text','text','text','text','text');
    const swiper = new Swiper(".swiper", {
        pagination: {
            el: '.swiper-pagination',
            clickable: true,
            renderBullet: function(index,className){
                return '<span class="' + className + '">' + '<div class="slider-text">' + (arrText_Slider[index]) + '</div>' + '</span>' 
            }
        },
        navigation: {
            nextEl: '.swiper-button-next',
            prevEl: '.swiper-button-prev'
        },
        autoplay: {
            delay: 4000,
            disableOnInteraction: false
        },
        loop: true,
        watchSlidesProgress: true
    });
document.addEventListener('mouseenter', event => {
    const el = event.target;
    if (el && el.matches && el.matches('.swiper-container')) {
                // console.log('mouseenter');
                // console.log('autoplay running', swiper.autoplay.running);
                el.swiper.autoplay.stop();
                el.classList.add('swiper-paused');

                const activeNavItem = el.querySelector('.swiper-pagination-bullet-active');
                activeNavItem.style.animationPlayState="paused";
            }
        }, true);

document.addEventListener('mouseleave', event => {
            // console.log('mouseleave', swiper.activeIndex, swiper.slides[swiper.activeIndex].progress);
            // console.log('autoplay running', swiper.autoplay.running);
            const el = event.target;
            if (el && el.matches && el.matches('.swiper-container')) {
                el.swiper.autoplay.start();
                el.classList.remove('swiper-paused');

                const activeNavItem = el.querySelector('.swiper-pagination-bullet-active');

                activeNavItem.classList.remove('swiper-pagination-bullet-active');
            // activeNavItem.style.animation = 'none';

            setTimeout(() => {
                activeNavItem.classList.add('swiper-pagination-bullet-active');
                // activeNavItem.style.animation = '';
            }, 10);
        }
    }, true);

和html

<div class="swiper">
            <div class="swiper-wrapper">
                <!-- Slides -->
                <div class="swiper-slide"><img src="img/slider/1.jpg"></div>
                <div class="swiper-slide"><img src="img/slider/2.jpg"></div>
                <div class="swiper-slide"><img src="img/slider/3.jpg"></div>
                <div class="swiper-slide"><img src="img/slider/4.jpg"></div>
                <div class="swiper-slide"><img src="img/slider/5.jpg"></div>
                <div class="swiper-slide"><img src="img/slider/6.jpg"></div>
            </div>
            <div class="swiper-pagination"></div>

        </div>
