Vue3 Uncaught TypeError: t is not a constructor

Question

I've been having this issue for a few hours now, I'm trying to use vue-flash-message in my Vue app, but it keeps throwing this error: 'Uncaught TypeError: t is not a constructor'. I don't know where, or how this is happening. This is my main.js, and I'm not actually using anywhere in the app yet. Would appreciate any form of help. Thank you

import { createApp } from 'vue'
import App from './App.vue'
import FlashMessage from '@smartweb/vue-flash-message';
import router from './router'
import store from './store'


const app = createApp(App);
app.use(FlashMessage);
app.use(store)
app.use(router)
app.mount('#app')
