        }
    },

You're using : on the v-model-attribute, which lets Vue think it's a binded prop with the name "v-model", rather than the v-model itself.

Replace :v-model with v-model:

<v-slider @change="setPosition()" :value="trackProgress" :v-model="percentage" thumb-label></v-slider>

should be

<v-slider @change="setPosition()" :value="trackProgress" v-model="percentage" thumb-label></v-slider>
