Does a Windows restart help?

[DragosMiloiuNXP]

@gjsjohnmurray, no, it doesn't. I restarted the computer two times. No improvement.

Might be duplicate of #125993.

[DragosMiloiuNXP]

@tamuratak, I do not think it is a duplicate of that one. The issue was not reproducible on 1.81 or earlier VS Code builds, and that issue was reported back in June.

[Guo-Chenxu]

Did you solve this problem ? I met the problem same as yours and have been troubled by this problem for many days.

I have tried:

1. reinstall vscode
2. kill the vscode process
3. reinstall extension (markdown preview enhance)
4. restart my windows
5. use code --no-sandbox to run
6. delete the cache in C:\Users\<user_name>\AppData\Roaming\Code

but they all seem not to work. And now, every time, I open my vscode to read markdown, I have to open twice to preview.

[Guo-Chenxu]

By the way, the time of start when vscode has problems seems to be slower than usual. I don't know why, but there may be some bugs in loading?

[DragosMiloiuNXP]

Issue is still reproducible on 1.82.2.

@Guo-Chenxu , yes, when VS Code has problems with opening webviews, it starts slower. When it starts normally (not slower than usual), the webviews work.

Related to #192493.

On 1.82+ and insiders, on Linux, VS Code has a startup slowdown in the init storage step 50% of the time, and it cannot open a webview afterwards when it is the case:

What	Duration	Process	Info
init storage (global & workspace)	1509	[renderer]	-
init workspace service	1495	[renderer]	-

Same problem on Linux (Pop!_OS 22.04 LTS) with vscode 1.82.2 when i open GitGraph. I have to restart vscode all time. This problem seems to happen since version 1.82 for me.

Error loading webview: Error: Could not register service worker: InvalidStateError: Failed to register a ServiceWorker: The document is in an invalid state..

[x-hgg-x]

The issue occurs because VS Code doesn't exit immediately after the last window is closed (#192742). Killing all the residual processes solves the issue.

A patch has been released in the last insiders version, and with it the issue doesn't occur anymore.

Is this issue resolved? Can someone confirm? DragosMiloiuNXP

I tested the issue on the insiders version and it seems to be fixed.

[ghost]

how to fix this in github.dev ?

[ssibrahimpur]

@mjbvz Any workaround for this issue at this point in time? Issue observed on 1.83.1 version

[dvins]

And on 1.84.2
