Erro ao adicionar o PropType - RESOLVIDO

Quando adiciona o PropType no componente tarefa, recebo o seguinte erro:

Module build failed (from ./node_modules/babel-loader/lib/index.js):
SyntaxError: D:\estudos\vue\alura-traker\src\components\TarefaComp.vue: Unexpected token, expected "," (11:19)

   9 |   props: {
  10 |     tarefa: {
> 11 |       type: Object as PropType<ITarefa>,
     |                    ^
  12 |       required: true
  13 |     }
  14 |   }
    at instantiate (D:\estudos\vue\alura-traker\node_modules\@babel\parser\lib\index.js:72:32)
    at constructor (D:\estudos\vue\alura-traker\node_modules\@babel\parser\lib\index.js:359:12)

Assim está meu componente:

import { defineComponent, PropType } from "vue";
import CronometroComponent from "@/components/CronometroComponent";
import ITarefa from "@/interfaces/ITarefa";

export default defineComponent({
  name: 'TarefaComp',
  components: {CronometroComponent},
  props: {
    tarefa: {
      type: Object as PropType<ITarefa>,
      required: true
    }
  }

});
