Slow to pick up block comment in JavaScript

[nguyendviet]

OS: MacOS Version 10.14.5
VSCode Version 1.36.0

I used to be able to type: /** before my function like this:

/**
const myFunc = (myparams) => {}

then VSCode will immediately return:

/**
 * 
 * @param {*} myparams 
 */
const myFunc = (myparams) => {}

Now after the update of VSCode (I assume), it's very slow to pick up the comment. I normally have to quit VSCode and restart it to make it work, but it's very slow, it takes up to 2 seconds to return the JSDoc comment.

Sometimes I got the message that Extension host terminated unexpectedly.. Here's the log:
