runtime-core.esm-bundler.js:40 [Vue warn]: Vue received a Component which was made a reactive object

vue3 [Vue warn]

```runtime-core.esm-bundler.js:40 [Vue warn]: Vue received a Component which was made a reactive object. This can lead to unnecessary performance overhead, and should be avoided by marking the component with markRaw or using shallowRef instead of ref.

<script setup>
import {ref} from "vue";
import Home from "./views/Home.vue";
import Users from "./views/Users.vue";
//selectPage默认值null
const selectPage = ref(null);
const changeSelectPage = (page) => {
  selectPage.value = page;
}
changeSelectPage(Home)
</script>

<template>
  <div>
    <button type="button" class="btn btn-primary" @click="changeSelectPage(Home)">首页</button>
    <button type="button" class="btn btn-primary" @click="changeSelectPage(Users)">用户</button>
    <!--动态组件-->
    <component :is="selectPage"></component>
  </div>


</template>
