When you import a core component such as StackLayout and you are also using it in the template, the application fails with this error:

Example:

<script lang="ts" setup>
import {StackLayout} from "@nativescript/core";
</script>

<template>
  <Page actionBarHidden="true">
      <StackLayout>
      </StackLayout>
  </Page>
</template>

This is somewhat expected behavior with script setup: https://vuejs.org/api/sfc-script-setup.html#top-level-bindings-are-exposed-to-template

Since the import matches the tag, and the component naming convention.

You could alias the import as a workaround:

import {StackLayout as NSCStackLayout} from "@nativescript/core";
