Can not select conda Python evironment as Python interpreter

Hi,
I open this issue as a follow up of [this issue](https://github.com/microsoft/vscode-python/issues/25814#issuecomment-4179181041).

When I try to select my conda environment in `Python: Select Interpreter`. It looks like it's not actually switching the interpreter.
The conda environment I would like select is `base (3.12.7) ~/miniconda3/bin/python`.
The environment in which the interpreter is "stuck" is `Python 3.12.3 /usr/bin/python`.

In the example below, plotly is installed only in the `base` environment.
It looks like it can't find plotly which makes me suspect that the interpreter is not actually changed.

Strangely, in the `Select Interpreter` menu, the grayed out text is actually correct.

So I'm not exactly sure what's going on but it would useful if my packages would be found again.
I'm on Ubuntu and I installed the pre-release version of Python environments (`1.27.10931008`) within code-insiders.

Many thanks,
