• OS and version: Windows 10
• Python version (& distribution if applicable, e.g. Anaconda): 3.8.1
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): venv

Actual behaviour

Steps to reproduce:

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

1. On Windows, select an interpreter and check the output in the developer tools. You will see a lot of "unknown" errors.
