Interpreter shown in the status bar is not the selected one on MacOS

Environment data

• VS Code version: 1.57.0-insider commit 54d33cf
• Extension version (available under the Extensions sidebar): 2021.5.821509413-rc
• OS and version: macOS Big Sur 11.2.3
• Python version (& distribution if applicable, e.g. Anaconda): 3.10.0a5 (global), 3.6.9 venv
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): venv
• Relevant/affected Python packages and their versions: N/A
• Relevant/affected Python-related VS Code extensions and their versions: N/A
• Value of the python.languageServer setting: Pylance

Expected behaviour

Interpreter shown in the status bar should be the selected interpreter.

Actual behaviour

Interpreter shown is whatever the extension could find (it's not even the interpreter I use in python.defaultInterpreterPath and I opted into all experiments), in this case /usr/local/bin/python3.

Notes:

• Opening a new terminal will activate the correct interpreter.
• Selecting a different interpreter in the quickpick will update the status bar to the correct one.
• Opening another Python file will also update the status bar.

Note the difference between the interpreter in the bottom left, and the current interpreter in the quickpick:

Steps to reproduce:

1. Open a Python project, install the extension, reload the window and wait for the extension to activate
2. Notice that the interpreter shown in the status bar is not the one selected for the project

Need to investigate to see if it's a mac-only issue.

[stevetwist]

Not sure if this is helpful, or what additional information I can provide, but I am experiencing this exact behavior on Windows 10.

When I first open a workspace the interpreter shown is a random interpreter VSCode found (it's not set for any of my workspaces). Opening another file then updates to display the correct interpreter, set for my workspace. From that point on (in the session) everything is fine.

Thanks,
Steve

Yep it is! Thanks for confirming that it doesn't happen only on macs stevetwist!
