[MyronLi]

Issue Type: Bug

If the workspace contains a project creating with create-react-app, intellisense is not working(always "loading....").

I also experienced the same thing

same thing here

I am in a similar state.
Even if you press ctrl + space, only loading is displayed, and it takes about 10 seconds until intellisence is displayed.
Also, the update of the underline meaning of the error warning in the source code is very painful, about 10 seconds later.
I've never had to wait on the same machine, on the same project.
typescript 3.7.3

There is no intellisense in the React file, other files are normal. The vue or angular files have not been tried!

[VipulSoni-Dev]

for me it works after installing npm and npm intellisense extensions in my new VSCode..
try this if you are working on react-native ,react , or node.js

@sonivipul89 Back to version 1.40 intellisense is work. This did not take effect in the latest version 1.41.
I had to disable automatic updates and keep them at version 1.40. Wait until officials fix the problem and then update to the latest version.

[VitaminCtea]

@MyronLi It's a project that's been generated with React scaffolding, But it doesn't have much to do with how the project is generated.
There should be a problem with the internal build of vscode, Look forward to the official restoration of it.

Note: In version 1.40, this problem did not occur

@MyronLi Is your core stored on something other than the c: drive?

[MyronLi]

Everything for vscode store on c: drive. @mjbvz

node version: v10.17.0 manged by nvm-windows. @mjbvz

There are two solutions to the problem of intellisense not working:

1. Back to version 1.40, and then disable automatic updates in the settings.json file.
2. If you're friends with version 1.41, you can fix the problem by installing the JavaScript and TypeScript Nightly plugin

Self test, both are effective. I hope I can help others who have the same problem as me

[MyronLi]

Thank you for feedback. @VitaminCtea
I had backed to version 1.40.

@VitaminCtea It's now normal after installing JavaScript and TypeScript Nightly .Thx

[VitaminCtea]

@MyronLi @zhanyuzhang Well done!
