Issue activating Python extension for Intellicode (looks like a venv interpreter detection issue)

Environment data

• VS Code version: Version: 1.54.3 (user setup)
• Extension version (available under the Extensions sidebar): v2021.3.680753044
• OS and version: Windows_NT x64 10.0.19042
• Python version (& distribution if applicable, e.g. Anaconda): 3.8.7 CPython
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): venv
• Relevant/affected Python packages and their versions: irrelevant
• Relevant/affected Python-related VS Code extensions and their versions: Python: v2021.3.680753044 with Intellicode: v1.2.12, also the pairing Python: 2021.3.658691958 with Intellicode: v1.2.11 exhibits the same issue
• Value of the python.languageServer setting: “Pylance”

[NOTE: If you suspect that your issue is related to the Microsoft Python Language Server (python.languageServer: 'Microsoft'), please download our new language server Pylance from the VS Code marketplace to see if that fixes your issue]

Expected behaviour

Intellicode loads properly

Actual behaviour

Error message as a notification : Sorry, something went wrong activating IntelliCode support for Python. Please check the “Python” and “VS IntelliCode” output windows for details.

Syntax coloration is partly broken (namely imports are not colored in green), autocompletion fails. The system python seems to work ok, but as soon as trying to change the interpreter there is an issue with the python interpreter not being recognized properly in the venv it seems.

Manually entering the path to the interpreter seems to work.

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

1. Set interpreter to venv for workspace (manually if it is not auto detected)
2. Close workspace
3. Open workspace
4. Issue is triggered

Experiencing the same issue.

Manually entering the path to the interpreter seems to work.

This worked for me, too. After executing the Python: Select Interpreter command from the command palette and specifying the right python interpreter, the syntax highlighting and the autocompletion recovered to normal.

This is probably stale as the issue did not seem to re-occur. Closing
