I had problems with the suggestions and the language server not working properly. Saw "TypeError: _0x2f33cc[(_0x1efd68(...) + _0x1efd68(...))] is not a function [...]" printed to the output of the Python Language Server. So I rolled back Pylance from v2023.10.50 to v2023.10.40, and now it works as intended. I'm not sure if it will work for you, but it might be worth a try.

Duplicate of #5009. We just shipped the fix for this in prerelease build 2023.10.53.
