This takes a long time for am empty TS file:

Steps to Reproduce:

1. Install NodeJS.
2. Create an empty folder. Open it with vsCode.
3. Create the below files with the exact content shown.
4. Run `npm i` in terminal to install packages.
5. Open and view `index.ts` file.
6. Do `ctrl+shift+p` and select `TypeScript: Restart TS Server`.
7. In the Status Bar, you would see `Analyzing 'index.ts' and its dependencies` (Source: TypeScript and JavaScript Language Features).

The `Analyzing 'index.ts' and its dependencies` spins for a very long time. The package we installed, has a lot of files, but it wasn't like this before. Things worked fine with even a ton of packages and TS files.

Here are the source files to reproduce:

`index.ts`: EMPTY FILE!

`package.json`:

```json
{
"dependencies": {
"phosphor-icons-svelte": "2.0.9"
}
}
```

`.gitignore`:

```
/node_modules/
```

Locking issues should be a crime! I mentioned the issue and it's not visible in that issue page! I can't even comment on that issue page. Don't lock issues just because you don't like them. Locking issues breaks so many basic and necessary functionalities of GitHub.

使用空的 index.ts、包含 phosphor-icons-svelte 的 package.json 以及列出的 VS Code 步骤重现延迟；首先重启 TypeScript 服务器并观察状态栏。将行为与相关 issue 244098 进行比较。完成标准是识别并解决该回归问题，使此最小项目的分析能够及时完成。
