[eleanorjboyd]

Thanks for reporting this. Could you provide a few more details to help us investigate?

• Where are the Python environments located (for example, .venv, Conda, pyenv, or another directory)?
• Which environments were detected before the VS Code update, and which are no longer detected?
• Can you still select one of the missing environments using Python: Select Interpreter or by entering its interpreter path directly?
• What are the values of python.defaultInterpreterPath and any python-envs.* settings?
• Please share the Python Environments output/logs after reloading VS Code.
• Does the issue reproduce in a new workspace, and does restarting VS Code change anything?

If possible, please also fill in the reproduction steps, expected behavior, and actual behavior sections.
