Description

I've created a thread on Microsoft's Developer Community.

A fix for this issue has been released in 17.14.7. You can find the thread here:

GitHub Copilot Chat in VS 2022 consistently fails with parsing error, making the tool completely unusable. The error occurs every time I try to ask any question in Copilot Chat.

When I ask any question in GitHub Copilot Chat, I get the following behavior:

Chat shows "Copilot generating response"
After some time, error appears: "error occurred while completing the task. try again"
This happens consistently with every question, regardless of complexity
The issue has been persistent for several hours

Troubleshooting Already Attempted

  • Signed out and back into GitHub Copilot
  • Restarted Visual Studio multiple times
  • Verified internet connection is stable
  • Checked GitHub Copilot subscription status (active)
  • Cleared Visual Studio cache
  • Tested with different types of questions
  • Verified no firewall/antivirus blocking

Has anyone experienced similar "Could not parse" errors with Copilot Chat? Any suggestions for advanced troubleshooting or potential fixes would be greatly appreciated.
