VS Code’s in-built terminal is slow or laggy on MacOS Big Sur

If you encounter an annoyingly slow or laggy Visual Studio Code terminal command executions on macOS Big Sur, you are not alone.

Fix it by entering the following command in your terminal:

codesign --remove-signature /Applications/Visual\ Studio\ Code.app/Contents/Frameworks/Code\ Helper\ \(Renderer\).app

Restart Visual Studio code.
