First Issue, didnt think these applied to me.

I believe these are commented out instructions. I didn't think these applied to me. Opening command pallet to run an issue from with in vs-code wasn't an option. It didn't show up as an available command in the command pallet.

Enable trace logging by adding "python.analysis.logLevel": "Trace" to your settings.json configuration file. Adding this will cause a large amount of info to be printed to the Python output panel. This should not be left long term, as the performance impact of the logging is significant.
Note: If you think a GIF of what is happening would be helpful, consider tools like https://www.cockos.com/licecap/, https://github.com/phw/peek or https://www.screentogif.com/ .

Code Snippet / Additional information

This is a very basic flask app for learning purposes, Code Snippets are probably not relevant.

[jakebailey]

We saw this during early development, but were never able to reproduce it except on one machine in debug mode.

Is there anything interesting about your machine? Extra anti-virus? Do other node-related processes work? I assume VS Code works otherwise.

[joshuamwolfe]

Hey.

I found a thread that I might have a bad download and that I should uninstall, then delete the file from ".vscode" file from the user/%username%/.vscodefile.

After I did that and re-installed. I had notifications appear. You should reload vscode (or) You should reload window. I did vscode reload everytime.

After I posted this; I hit reload window and everything seems to be fine. I included strange events in txt file (attached) and a screen of what I think my processes were at the time. I'll try to recreate and update this thread asap.

If things stay fine and we cant come up with anything relevant I'll close the issue.

[joshuamwolfe]

I just fired up my python project and it happened again.

Which event log section should I look at? The text file events came from (event viewer > custom views > admin events)

[joshuamwolfe]

Just reinstalled the extensions, no error yet. I use python formatter black, I have it installed globally so I didn't think I needed to install, but vscode asked me if I wanted to reinstall. Said yes. Seems to be working again. #fingerscrossed

[realcy]

I meet the same problem after I upgrade to 2021.6.0 version. Then I downgrade to 2021.5.4, the error doesn't show.

This is a month old closed issue. Please file a new issue with the template filled out; the python logs would also be helpful.

[Lakitna]

It looks like I'm running into the same issue...

This logging repeats for every startup attempt.

Update: False alarm, there was a config issue due to a renamed VSCode workspace file.

[jakebailey]

Update: False alarm, there was a config issue due to a renamed VSCode workspace file.

I'm curious about this; can you elaborate on this? What was incorrect and what did you do to fix it? We haven't had a way to reproduce this since we first saw it.

[Lakitna]

The workspace file was rename from, let's say, foo.code-workspace to bar.code-workspace. It looked like that when I switched branches the workspace config was left in a sort of half-configured state causing the unexpected behavior.

I fixed my issue by opening VsCode with the new workspace file.

This probably won't help anyone else though :(

[jakebailey]

Yeah, unfortunately not; I can't see how a VS Code specific file would cause this odd node+Windows failure; it's not the same process.

[jakebailey]

We can't reproduce this, so I don't know how we can fix it. As far as I can tell, it happens only on some Windows machines and only rarely.

VS Code has also updated their version of Node, which I'm hoping fixed this in the meantime.

[vtjnash]

This looks to me like a kernel bug, but I have found a workaround for this issue for programs that use libuv, such as VSCode / nodejs: libuv/libuv#4152

The procedure to reproduce it are to:

1. Call CreateJobObjectW to make a new job handle (this succeeds)
2. Call CreateProcess on a Windows Store app (this succeeds)
3. Call AssignProcessToJobObject on the resulting hProcess (this fails with ERROR_ACCESS_DENIED)
4. Call CreateProcess on a desktop app (this succeeds)
5. Call AssignProcessToJobObject on the resulting hProcess (this fails with INVALID_PARAMETER)

[deepak1556]

Thanks @vtjnash for looking into this issue and addressing it! didn't realize windows store app would be the trigger and successive CreateProcess calls would be affected. I was trying to get a minimal repro but now I see why that didn't work microsoft/vscode#186912 (comment)

[vtjnash]

I was fortunate to have been given a much smaller reproducer. I only found this issue because I was searching for people who had solutions to it, and only came across a few places where people had had the same problem. Do you have a contact in the kernel team to ask whether they could see if this is a kernel issue or whether they could add a clarification to the documentation for AssignProcessToJobObject about this case?

[deepak1556]

Don't have any known contacts, but I can ask around.
