[nils-soderman]

Environment data

• Language Server version: v2024.3.1
• OS and version: Windows 10
• Python version (& distribution if applicable, e.g. Anaconda): Python 3.9.2

Code Snippet

example.code-workspace

{
    "folders": [
        {
            "name": "[ --- Hello World ---- ]",
            "path": "."
        }
    ]
}

Repro Steps

1. Create a VS Code workspace with the settings above.

2. Open a python file in the workspace to make sure Pylance extension initialize. Then check the Python Language Server output logs.

Expected behavior

No errors

Actual behavior

All settings are not properly read, and e.g. python.analysis.extraPaths might not be resolved (sometimes they still get resolved, and sometimes not).

Logs

I have recently encountered this issue on two separate computers, starting sometime in late March. Thus, it is likely that this issue is caused by a relatively recent update.

Thank you for the report! Given our current limited resources, it's unlikely we will be able to fix this issue in the near future. We're closing it so we can focus on higher priority issues. However, if this is a critical issue for you let us know and we can reevaluate. Thanks!
