@vkukk We use an external library when you select Jedi ( https://github.com/pappasam/jedi-language-server ). This particular issue seems to be with the pygls library, please file an issue in the repo https://github.com/openlawlibrary/pygls. Since this is python 3.11, I think support for it is still being worked on. This is likely openlawlibrary/pygls#234
