Does the problem also happen if you launch with all extensions disabled?

[StebanDev]

I have the exact same problem, tried in stable version and in insiders too. Got all extensions disabled, it is happening after 1.41 update, it works only for the first suggestion and then doesn't work anymore.
I noticed one of the code processes keep with 25% avg cpu load

i have same behavior, works only for first suggestion and without extensions too

[RMacfarlane]

@hrds What languages are you coding in?

[hrds]

@RMacfarlane JavaScript in this case, but it's problem with suggestions overall.

[St-Permiakov]

Same issue here.
JavaScript, with extensions and without.

Intellisense stops responding alongside some other functions (like GoTo).
I guess it has something to do with imports and code size (removing most part of imports from js file may have helped), but I'm not sure.

Downgrade to 1.40 helps for sure, so it's a valid tmp fix.

Please, let us know when the issue is resolved somehow.

[aboe026]

I'm seeing the same behavior as well. uninstalling vs-code then installing 1.41 did not seem to help.

[drillprop]

Same for me. When i do "Restart TS server" for a one import it works, but then stops again and showing 'No Suggestions'.

[mjbvz]

@hrds Do you see this issue in other files, such as json or html?

Also does this reproduce with all extensions disabled?

[drillprop]

I found workaround here: microsoft/TypeScript#35716 (comment). At least it works for me. It seems autocompletion with this extension works even better than before.

[jonas-wu]

mark，I have the same problem.

[bailiyang]

Autocomplete back again now
what's happen

[hrds]

Autocomplete back again now
what's happen

Same, I'm checking right now, everything works. idk what you did, but thanks

[dandmcd]

I'm not having the same luck as the above 2, Intellisense is just showing Loading while hovering, and not providing autocomplete. Extensions or not it is failing. I am working with JS files, it appears like it is breaking when a file can be auto-imported.

I restarted VSCode, and even rebooted to no avail. I updated perhaps 2 days ago, this error was not present until today. I was able to produce a Typescript server error in the exthost log. Turning off all extensions did not solve the issue, but the error was gone.

Intellisense doesn't work for me either on 1.41.0 (win 10 1909) with a react-native project. I had to downgrade to 1.40.2 where ac is instant. If I install the typescript@next plugin for 1.40.2 then the same happens, no intellisense anywhere (thats a nightly build so maybe just broken atm, otherwise related).

[alexdima]

Hey, does anyone here have any steps or any commonalities? Is everyone having trouble with react based projects only?

[St-Permiakov]

Well, not React based, but JS + ES6 Modules based.
Can't tell for others.

[drillprop]

@alexdima I tested on typescript and javascript react based projects, it's not working. For some reason in typescript projects when i enable typescript@next extension, intellisense and autoimports works fine.

[dandmcd]

@alexdima I've only tried with React JS files thus far. Everything seems to work fine for the first minute or so, and than Intellisense starts failing. I'm not sure if there is a way to get a log of Intellisense, but I didn't find anything digging around the dev log file folder.

[mckennatim]

For me it autocomplete stopped a while ago on code insiders, switched to regular and it came back until 1.41. Just downgraded to 1.40 regular and all is good. 1.42 insiders is also broken

[fanzkday]

Me, too. But, can use lower version, 1.30 is working!

[crysispht]

I use typescript@next extension and choose the version of 3.6.*, it seems to work

[jonas-wu]

I added extension(JavaScript and TypeScript Nightly), and the problem is gone

[alexdima]

@mjbvz From the comments, I think this is a problem with the specific tsserver version we shipped in 1.42

[Cellv2]

Check the drive that your project is on. If it's on a different drive to the one you put your VS Code install on, try putting it on the same drive

This was raised a few weeks ago on insiders (#85889) - is down to the TS version. VS Code ships with TS 3.7.3, which has the issue

Fix is there (microsoft/TypeScript#35512), but it's not out the gates yet

Doing npm i -D [email protected].* then opening VS Code, bringing up the command palette (F1) > select typescript version and using workspace version was a workaround for me

[mjbvz]

@hrds So has the issue been fixed for you? Are your projects stored on non-c drives on windows? If so, please try upgrading your workspace to use typescript@next by installing this extension

[aboe026]

i was seeing this issue and my projects are on a different drive than vscode is installed on, so there is probably some credence in that being the culprit. I've since downgraded to 1.4.0.2 so I cannot attempt the typescript workaround

[Cl00e9ment]

For me the issue was a bit different: Editor: Accept Suggestion On Enter has been put to off after updating. Putting to on again fixed the problem.

[codenoobforreal]

Use typescript@next is work for me!

[mjbvz]

Closing this as a likely duplicate of microsoft/TypeScript#35512

To workaround this, use typescript@next by installing this extension

[prabhaw]

i was seeing this issue and i install older version 1.40 it work fine for me.

[lomeat]

I added extension(JavaScript and TypeScript Nightly), and the problem is gone

WOW. Its worrks. Thank you man!

P.S. I honestly don't understand why I should install noname extension to use default features of editor.

[gjsjohnmurray]

P.S. I honestly don't understand why I should install noname extension to use default features of editor.

As I understand the situation, that extension allows a 1.41 user to benefit in advance from a set of fixes that will land in 1.42, expected to ship later this week. @mjbvz is this true?
