Neither 'Start Terminal REPL" or "Run Selection/Line in Python Terminal" work

[yelled1]

Type: Bug

Behaviour

Neither 'Start Terminal REPL" nor "Run Selection/Line in Python Terminal" works with venv

Steps to reproduce:

1. After highlighting code selection
2. Shift+Enter or Explicitly Right Click 'Run Python'->'Run Selection/Line in Python Terminal' launches REPL. terminal
3. In addition, when I Ctrl+P and select: 'Python: Start Terminal REPL'
   I get following from the Terminal below:

pyenv shell vtx11
/home/hxxx/.pyenv/versions/vtx11
hxxx@VSS-RM:~/Prj/VertexAi$ pyenv shell vtx11
hxxxn@VSS-RM:~/Prj/VertexAi$ /home/hxxx/.pyenv/versions/vtx11
bash: /home/hxxx/.pyenv/versions/vtx11: Is a directory
hxxx@VSS-RM:~/Prj/VertexAi$ 

(above is from WSL but Windows 11 with Conda does same thing: note 3rd line where directory rather than python.exe is specified)
I tried deleting all other "shift+return" combinations
Tried on conda & pyenv on WSL2 Ubuntu / only conda in Windows
Ubuntu 24.04.3 LTS (GNU/Linux 5.15.167.4-microsoft-standard-WSL2 x86_64)

For some reason when I choose non virtual env python on Ubuntu it works

/bin/python3
hxxx@VSS-RM:~/Prj/VertexAi$ /bin/python3
Python 3.12.3 (main, Aug 14 2025, 17:47:21) [GCC 13.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> def generate():
...   client = genai.Client(
...       vertexai=True,
...       project="cewlp-ce2bc",
...       location="global",
...   )
... 
>>> 

Note: Run Python File in Terminal works

output of .vscode/settings.json

$ cat .vscode/settings.json

    "python-envs.defaultEnvManager": "ms-python.python:pyenv",
    "python-envs.pythonProjects": []

Can you try setting "python.useEnvironmentsExtension": false in your settings.json and see if you can still repro?

[yelled1]

Worked in WSL & likely in Win11, but had conda config issue, which is likely conda config issue. Much appreciated & pls close,
