Can't select Anaconda virtual environment Python 3.10 interpreter

[duncantop]

VS Code version

1.62.0

Extension version

v2021.11.1422169775

OS type

Windows

OS version

10

Python distribution

Anaconda

Python version

3.10.0

Language server

Pylance

Expected behaviour

I should be able to see and select my py310 anaconda python installation.

Actual behaviour

When selecting a python interpreter, I see my list of non-3.10 environments but only briefly see my py310 environment at the bottom of the list before it disappears. When I have forced the interpreter to my py310 install vscode still asks me to select an interpreter.

Steps to reproduce

No matter how I create a new anaconda environment with python 3.10, the same thing happens. I have tried making new non-3.10 environments and they show up in the interpreter list and are usable. Issue seems exclusive to python 3.10.

@duncantop what happens when you run from a command prompt outside of vscode.

The system cannot find the path specified.

If I type out the tildes:

I have same problem

[Francois-Bergeron]

Same issue here, even when setting the 3.10 conda environment as default interpreter.
The 3.10 environment is working fine on other IDEs, and other environments (below 3.10) are working perfectly in VSCode.

[kochuyt]

On Win10, using miniconda and have the same issue with 3.10 not showing up
(pre 3.10 versions show up as expected)

[karthiknadig]

This is strange, running anything with conda python 3.10 seems to be not working. But 3.9 it does return what we expect.

> conda create -p .venv python=3.10
> .venv\\python.exe -c "import sys;print(sys.executable)"

> conda create -p .venv2 python=3.9
> .venv2\python.exe -c "import sys;print(sys.executable)" 
C:\GIT\repro\conda1\.venv2\python.exe

The reason this is not working is because we are not able to get any info from the python.exe. when we run the script below it is not returning anything with conda python 3.10.

> .venv\python.exe "C:\Users\Karthik Nadig\.vscode\extensions\ms-python.python-2021.11.1422169775\pythonFiles\interpreterInfo.py"

but it does with 3.9:

> .venv2\python.exe "C:\Users\Karthik Nadig\.vscode\extensions\ms-python.python-2021.11.1422169775\pythonFiles\interpreterInfo.py"
