Svelte - getting ERR_MODULE_NOT_FOUND from svelte.config.js

I am learning Svelte currently and I am not sure what is causing this error. The error exists within every one of my .svelte files, though it is not actually preventing the app from running.

I am using VSCode and at the top of each of my .svelte files, if I hover over <script lang="ts">, it shows the following error:

Error [ERR_MODULE_NOT_FOUND]: Cannot find package '@sveltejs/adapter-static' imported from svelte.config.js

In my svelte.config.js I have this import:

import adapter from '@sveltejs/adapter-static';

And in my package.json I have "@sveltejs/adapter-static": "3.0.1" under devDependencies

I have tried restarting VSCode, rerunning pnpm install and a handful of other suggestions I found while searching this error, but so far I haven't had any luck getting the error to go away.

Any ideas?
