i was working on a vs code extension, it was using the inbuilt typescript language server (tsserver.js)
But suddenly today i got an error VS Code’s tsserver was deleted by another application such as a misbehaving virus detection tool. Please reinstall VS Code.
I Reinstalled vs code , and checked these steps to ensure that tsserver.js was present . but now on running my extension , i get this warning The task ‘npm: watch’ cannot be tracked. Make sure to have a problem matcher defined,
and i no longer can use the typescript language server.
Kindly Assist.

I validated that the tsserver.js file is present in /Applications/Visual Studio Code.app/Contents/Resources/app/extensions/node_modules/typescript/lib/tsserver.js.
Following the steps from this discussion.
But i still cant use the typescript language server.
