Thanks for your feedback! We have recently released a new and more performant language server called Pylance which likely solves these issues you are reporting.  You can download Pylance from the marketplace and install it alongside the core Python extension. Because our team's development efforts have shifted to support the new language server, we'd encourage you to try it out.

Karthik Nadig (@karthiknadig) Thank you for your reply. I have switched the language server to Pylance, but encountered the same problem.
