VS Code extension host keeps terminating on Windows 11

Hello,

I’m experiencing an issue where the VS Code extension host keeps terminating. Because of this, several AI extensions, including GitHub Copilot, OpenAI Codex, and Claude, are not working properly.

I’m unable to:

  • Sign in to the extensions
  • Start a chat with GitHub Copilot
  • Use Codex, Claude, or other AI agents

So far, I’ve tried:

  • Completely uninstalling and reinstalling VS Code
  • Uninstalling and reinstalling the affected extensions

However, the issue still persists.

I’m using Windows 11. Has anyone encountered this problem or found a solution?
