Hi @frl3, thank you for reaching out!

Which version of the extension are you using? And does it happen with older versions of the extension?

[frl3]

version 3.9.4 -
downloaded from phyton.org
installed in user AppData folder.
so it's a per user installation.

should I change the installation to full system installation - Program Files

that's the only version installed.

Hello, this is the info for the version of Python you have installed, not the version of the Python extension in VS Code.

To find your extension information, go to the "Extensions" tab in VS Code, find "Python" and click on "Copy":

To try out other versions of the extension, you can follow the prompts from "Extensions: Install Specific Version of Extension..." in the command palette:

Or you can open the extensions side bar, click on the settings for the Python extension and pick "Install Another Version...":

Same response, prolonged loading, eating up my memory. Slowing down my whole desktop system.

[frl3]

should I try another?

[kimadeline]

No that'll do for now, thanks!

[frl3]

@kimadeline how's your analysis going?

[kimadeline]

Unfortunately we don't give out updates on work.

[frl3]

so how will i solve this problem?

[kimadeline]

You can try using older versions of the extension until you find one that works for you while we investigate the problem you're facing.

Hi @frl3, thank you for your patience!

Checking the cpuprofile you posted, it seems like the new discovery code was endlessly looping. We fixed a few issues with it in the most recent release, could you give it a try?

If not, can you try adding the following to your global settings.json and try to activate the extension again:

"python.experiments.optOutFrom": [
        "pythonDiscoveryModule",
        "pythonDiscoveryModuleWithoutWatcher"
    ],

Thanks!
