Steps to reproduce

is triggered by code suggestions with any python code and then it crashes the extension.

in a new window, new file type from datetime import and trigger code suggestion, no suggestions are show and extension is crashed

Also found this https://github.com/microsoft/vscode/issues/110467 but i don’t have two versions installed at the same time, and I’ve checked inside the container too.
