I remove last extra comma from “C:\Users[username].vscode\extensions\ms-python.python-2019.4.11881\package.nls.[language].json.” and restart vs code. it works. I’m using Japanese.

[charlesHsuGG]

also similar issue too. i fix this to early extension version, i think this problem on new extension version, maybe wait someone fix this bug. and dont forgot close auto update on vs code.
