How to Fix Visual Studio Code Extensions Not Working (Complete Guide)

If your extensions are not working in Visual Studio Code, you are not alone. Many developers face issues where extensions fail to load, crash, or simply do not activate.

In this guide, we will go through the most common causes and fix them step by step.

1. Restart Visual Studio Code

The simplest solution is often the most effective. Extensions sometimes fail due to temporary glitches.

  • Close VS Code completely
  • Reopen it
  • Check if extensions are working

2. Check extension compatibility

Some extensions may not support your current version of VS Code or your operating system.

  • Update VS Code to the latest version
  • Check extension requirements in the marketplace

3. Disable conflicting extensions

Sometimes multiple extensions interfere with each other.

  • Disable all extensions
  • Enable them one by one
  • Find the conflicting extension

4. Reinstall the extension

If an extension is corrupted, reinstalling usually fixes the issue.

  • Uninstall the extension
  • Restart VS Code
  • Install it again from the marketplace

5. Check Developer Console

VS Code has a built-in developer console where you can see errors.

  • Go to Help → Toggle Developer Tools
  • Check error messages

Final Thoughts

Most extension problems in VS Code are caused by version mismatch, conflicts, or corrupted installs. Once fixed, your development workflow becomes smooth again.
