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:

{
    "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.
