Visual Studio Code (VS Code) is a popular code editor known for its lightweight and powerful features. However, like any software, it can sometimes encounter issues that hinder its performance. One such issue is the “Another Instance of Code is Running But Not Responding” error, which can be frustrating for developers. In this comprehensive guide, we’ll explore the possible causes of this error and provide step-by-step solutions to resolve it.
Understanding the Error
The “Another Instance of Code is Running But Not Responding” error occurs when there is a conflict between multiple instances of VS Code. This can happen if you attempt to open a new instance while one is already running, or if the program is struggling to respond due to high system resource usage.
