Vscode: Extension Host is unresponsive

[st-schneider]

Issue Type: Bug

It currently seems to be the case that the extension host is unresponsive frequently.

When you open up the Running Extensions window it turns to

And after a while this process starts over

As a per session workaround, what works for me is to go to extensions, select the ... menu and Disable All Installed Extentions, reload (on any one of the disabled extensions), once reloaded, Enable All Extensions then Show Disabled Extensions and hit reload on any of the extensions.

Duplicate of #58672

Please update, a new build with a fix is available. Sorry about that!

[Eventyret]

@alexandrudima ~I still have the same issue even after the new build.~

Update: Seems after doing what @clintwood suggested after the build fixed it for me.

[alexdima]

Please keep an eye out and let us know if you still see this false positive after you have updated and if you have some good steps.

If you see the popup you can also take a peek at Task Manager and check, perhaps the extension host is indeed busy and it wasn't a false positive after all.

In any case, if you see it please reach out. Thank you!

[clintwood]

The update works for me - thank you!

[Eventyret]

@alexandrudima so i found out if you have the extentions window open. You install or uninstall reload extentions etc it will fire. and keep looping.

What data did you want me to get you ?

[alexdima]

@Eventyret Sorry for not being clear. After updating to the latest Insiders (kill all running processes of VSCode), do you still see the following popup:

If you do, can you please open a new issue with your environment, installed extensions, and perhaps some steps if any steps are required to reproduce.

[Eventyret]

@alexandrudima i feel this can be closed. I will open a new issue and refer to this if it happends again (have a computer without the update so will update and test it straight off there in a few hours)

Thanks again.

[lyndonjohn]

The last update fixed the issue. 👍

[joelgetaction]

I still see this issue constantly. I have upgraded to the latest build and it did not help. I am on Version 1.28.0-insider (1.28.0-insider) at af3614909b837c46a260666cb7baab7a8468a9c8.

Any suggestions? This is making it difficult to use VSCode because all my save on format, etc is all messed up and it's really slowing me down ... :-(

I am on macOS by the way. Looked like the screenshots above might be from Windows.

[alexdima]

@joelgetaction Here is how you can profile extensions -- https://github.com/Microsoft/vscode/wiki/Performance-Issues#profile-the-running-extensions -- use those steps to identify which extensions consume a lot of CPU.

[DuncanFaulkner]

This seems to be happening more, updated this morning to latest insiders version, and get message popping up every 15 / 20 minutes or so. not installed any new extensions recently. would be nice for the pop up to mention which extension was having an issue.

I am seeing this way more often as well lately. It got so bad that I had to switch back to the regular non-insiders build and that build had no issues. Note that with the same exact setttings and installed extensions, the insiders build had serious issues with the extension host while the regular build did not. So the issue definitely seems to be with the insiders build ...

Still happening here. Also search and quick open seems to be buggy :(

[icyJoseph]

I've got the same problem now too. In the two computers I own, both with the insiders build. It seems that killing the process fixes it temporarily.

[monirkohi2006]

This is annoying as hell, every few minutes the notification pops up. Started seeing the problem after upgrading to 1.28. Had to roll back to 1.27.2. The problem went away.

[nicubarbaros]

Same here Version 1.28.0

[shermendev]

Same, have to restart a couple times. v1.28.0

[jsharer2]

Same here, also v1.28.0

[simioluwatomi]

Same here, v1.28.0 (user setup). Very annoying!!!!

[icyJoseph]

Same here, again, for the n-th time, latest vs code insiders and regular. You managed to bloat VS Code out of proportion.

[ionling]

same here, also 1.28.0

[ionling]

same here, also 1.28.0

It may take several minutes to get normal after I click Restart Extension Host button.

[Da13Harris]

I'm also seeing this (1.28.0 user setup) every time I start up. If it's actually related to the extensions, these ones are common between mine and the two sets listed above by @NicolasReibnitz and @monirkohi2006.

CoenraadS.bracket-pair-colorizer
eg2.vscode-npm-script
esbenp.prettier-vscode
robertohuertasm.vscode-icons

I also have this problem with 1.28.0 (windows 64 bits).

From that list I have just CoenraadS.bracket-pair-colorizer

[ryanaltvater]

@alexandrudima This issue has completely killed my editor/workflow. I tried downgrading, but 1.27.2 also had a similar issue where the Extension Host was terminated. From the list above, I have bracket-pair-colorizer, but I noticed an issue where the project-manager extension seemed to bug out as well. So I tried disabling that as well and I'm still getting the unresponsive issue. Restarting the extension host just reproduces the popup again 30-60 seconds later.

VS Code is unusable in this state, please fix this asap! :(

[MAQ7]

Same issue here as well :(

[elmergomez]

No matter what I do unresponsive issue continues popping up :(

[mikelnorth]

The same issue, if it keeps happening I will have to try and uninstall and reinstall vs code entirely.

[nicubarbaros]

Is there a way to go back to the previous version of VS Code?

[wechuli]

@nicubarbaros , Not sure if this functionality is inside vs code itself but you can download a previous version and reinstall vs code- it will retain all your settings and extensions. Here is a link to previous versions, the August release should be okay. https://code.visualstudio.com/updates/v1_26

[lolimay]

As a per session workaround, what works for me is to go to extensions, select the ... menu and Disable All Installed Extentions, reload (on any one of the disabled extensions), once reloaded, Enable All Extensions then Show Disabled Extensions and hit reload on any of the extensions.

Thank you! Your solution is quite useful!

[NicolasReibnitz]

Strangely enough it stopped bugging around since yesterday evening. The message that came up every ten minutes or so didn't come up since.
I keep my fingers crossed.

[t0mpy]

This is the exact problem my friend and I are having when collaborating with VS live share.
As soon as he minimises the project it throws the error and I can no longer do anything or view the localhost. Baffles me that this is even a topic of discussion and wasn't sorted with the update.

[shakeelosmani]

It is still the same for me, extremely frustrating it has been since last couple of days.

[jony4]

same for me

[mikecarr]

I am seeing some extensions taking a while to activate (~14 seconds) which correlates to the Unresponsive popup. Is the extension loading blocking?

[hessnd]

I have noticed the extension host going unresponsive consistently when having a typescript file open, then opening an html file in a second window pane. It seems that the process Initializing JS/TS Features may be causing this as that process is running for a long time in the bottom status bar.

[auchenberg]

We have pushed a fix today to reduce the confusion about the unresponsive notification. See https://github.com/Microsoft/vscode/issues/60318

[Greyze]

For me it's more annoying than anything because you can't stop them from appearing. My laptop is slow so it takes some time to load all extensions. I always get the 2 msgs (extension host is unresponsive, is now responsive).

I already knew code takes time to load on my machine and I know when it's ready and working. I don't need the constant notifications. They also don't go away by themselves so I have to click them away every single time I load code.

Need an option to disable these extension host notifications
