@mjbvz Intellisense and go to definition both aren't working since after the update.

Edit: ts-server

I have the same problem today when VSCode update to version 1.33. I have been downgrading to version 1.32.3 and stop the option automatic update checking. It works fine while we are waiting for the hot fix from the VSCode team.

Same problem after update

Same problem, however it also reproduces on 1.32 if I select the workspace Typescript version (3.4) instead of the internal VSCode version (3.3). What I do is I open a tsx file, start typing something like props., press Ctrl+Space to see the autocomplete list, and all I see is "Loading...", at this point the autocomplete stops working across the whole project, and the "Go to definition" feature stops working too.

I was looking through the extension host log and saw and error that reads:

[error] Error: TypeScript Server Error (3.4.1)
Debug Failure. Expected 1 === 2. Registered script kind should match new script kind. <path to file>

And a bunch of:

[error] Error: TypeScript Server Error (3.4.1)
Debug Failure. Expected <# greater than 190> <= 190

Not sure if this helps
