Virtual environments not found

[mgeorge-is]

Type: Bug

Behaviour

Hatch virtual environments are not displayed when using the command palette Python: Select Interpreter (or similarly when using the Jupyter extensions Select Kernel option).

Steps to reproduce:

1. Update the VS Code python extension to 2024.18.0 or later.
2. Using hatch env create, create multiple virtual environments. By default they are placed in the .hatch directory of the workspace root.
3. Open command palette Python: Select Interpreter (or Jupyter extension Select Kernel) and local environments will not be listed.
4. Revert VS Code python extension to 2024.16.1 and restart and the environments are displayed as expected.

Diagnostic data

@mgeorge-is Is your locator native or js?

@anthonykim1: js (edit: this setting is for version 2024.16.1 which I have pinned so I can continue working. It is native if I update to 2024.18.0 (not working)).

I'm also experiencing problems with the python.locator setting. When set to native PET.EXE ist blocked from execution by AppLocker. There is an entry in the log files, but no indication in the GIU. I my case, no python runtimes could be found. Not even the runtime installed by VS Code itself. VS Code is a system installation, but PET.EXE is in my user profile where the python extension lives.

@mgeorge-is Does it work if you select it by navigating to it?

@lvm-1896 You may need to add either Microsoft Publisher or the specific pet file as an exception to AppLocker: https://learn.microsoft.com/en-us/windows/security/application-security/application-control/app-control-for-business/applocker/configure-exceptions-for-an-applocker-rule

Ran into this issue too on a brand new install of VSCode and vscode-python extension. What helped was switching locator off of native to js (and I restarted VSCode for good measure too).
