Hi,

Unfortunately, we were not able to reproduce this issue in the latest Metronic version. These imports don't throw any errors. It might be related to your Visual Studio Code used extension or configuration. Could you please specify which vue extensions are you using in your Visual Studio Code?

You might have an error with Visual Studio Code when using a Volar extension it might highlight some components, to fix this you can refer to the GitHub issue below.

It works in the projects here, tested in version 8.20 metronic, vue3.

Create a file at:
src/shims-vue.d.ts

Code:
declare module '*.vue';
