'PropType' only refers to a type, but is being used as a value here.

<script lang="ts" setup>
import { defineProps, PropType } from "vue";

interface Params {
  id: number;
}

const props = defineProps({
  msg: {
    type: String,
    required: true,
  },
  params: {
    type: Object as PropType<Params>,
    default: {},
  },
});
</script>

I don't know how to change to succeed.

import type {... } from 'lib'

This is really great. Thank you

Try using -
params: {
type: Object as () => Params,
default: {},
},
