We are frequently (to an unusable level) seeing the following error, both on latest release and pre-release in VS Code:

[ERROR] [default] [2023-08-28T10:36:53.762Z] GitHub Copilot could not connect to server. Extension activation failed: "Promise.allSettled is not a function"

VS Code:

Version: 1.81.1 (user setup)

GitHub Copilot: v1.105.364

I've signed out of Copilot in VS Code and signed back in. I've tried disabling and re-enabling, restarting VS Code, restarting the PC. Nothing solves this error. It is frequent enough that essentially we can't use Copilot. It is in a failed start more often than running.

Hi @kmcconnell ,

Thanks for reporting the issue and sorry for the inconvenience caused.

I have asked my team internally to take a closer look at the error. We will get back to you soon.

Hi @kmcconnell ,

We believe that this error is from Copilot Chat extension.

Could you confirm that the error is from Copilot extension or Copilot Chat in VSCode?

Thanks!

I am seeing the same issue as the OP and I do have Copilot Chat extension installed. I disabled Copilot Chat (and Copilot) extensions and the error is not reoccurring.

Indeed the problem is from the copilot chat extension, and I have noticed in my case that this error only occurs when I open a project containing XML files. I really hope this helps to determine the root cause of this error.

Same for me, still appears with that error, when opening XML files
