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.

In the meantime, I'll transfer this issue over to the Microsoft Python Language Server repo for tracking. If you try out Pylance and this issue persists, you can open an issue on the pylance-release repo.

@karthiknadig thanks! As I mentioned in the OP, I wasn't able to find pylance in the marketplace. I tried downloading the pylance vsix and then installing that but that completely broke my vs code. I found that the version I installed was the open source one and instead installed the Microsoft branded version via the visual-studio-code-bin on AUR and now it works just fine again. Not sure why it broke in the first place though, since it did at one point work before this week.
