0.38.4 causes errors when ts files import vue files

[Zazcallabah]

Last week my vue router config worked fine. Today, the router.ts file is full of errors.

Specifically, it seems that in a typescript-file, any imports of vue-files give the error Cannot find module '../views/HomeView.vue' or its corresponding type declarations.

This happens in all my vue projects. It also happens if I reinstall a clean vscode and create a new vue3 project with npm init.

Steps to reproduce

From a clean vscode install:

npm init vue@latest

√ Project name: ... vue-project
√ Add TypeScript? ... Yes
√ Add JSX Support? ... No
√ Add Vue Router for Single Page Application development? ... Yes
√ Add Pinia for state management? ... Yes
√ Add Vitest for Unit Testing? ... Yes
√ Add Cypress for End-to-End testing? ... No
√ Add ESLint for code quality? ... Yes
√ Add Prettier for code formatting? ... Yes

cd vue-project
npm i
code .

>> "trust authors"
>> "install recommended plugins"

Then open any ts-file in vscode. (ex ./src/router/index.ts)

versions:

• npm 8.12.1
• vue 3.2.37
• vscode 1.69.0
• vue.vscode-typescript-vue-plugin 0.38.4
• vue.volar 0.38.4
• vite 2.9.12

To clarify, it is vue.vscode-typescript-vue-plugin that causes the issue - or rather, downgrading that extension to 0.38.3 makes the issue disappear.
