・We cannot support operation in a CUI environment even if you contact us.

・If you develop using anything other than Visual Studio Code in a GUI environment, we cannot support it, so we recommend using Visual Studio Code.

・You must use Visual Studio Code 1.85 or earlier. Please obtain 1.85 from here. You will also need to downgrade the .devcontainer extension to 0.327.0.
Also, automatic updates are enabled in Visual Studio Code by default, so go to File -> User Preferences -> Settings and set update: Mode to none.
