Describe the bug / provide steps to reproduce it

I cannot use GitHub Copilot as LLM provider in the Assistant Panel, even though I am logged in and the inline suggestions are working.

What I did:

• click on the Copilot icon in the bottom-right corner, and follow the instruction to login
• The Copilot icon reflect the fact that I am logged in, and the inline suggestions when I am editing a file are working
• I open the Assistant Panel and go to "Configure Providers", here Copilot shows a "Sign in" button
• If I click on the button, a pop-up appears saying "Copilot Enabled!"
• However, when I open a new chat I get a warning "LLM provider is not configured" and I cannot use the chat

I also have this in my settings (automatically added by Zed)

  "assistant": {
    "default_model": {
      "provider": "copilot_chat",
      "model": "gpt-4o"
    },
    "version": "2"
  },

I am experiencing this problem on macOS Sequoia aarch64.
I am also logged in with the same Copilot account on an Intel Mac (macOS Sonoma) and a workstation with Ubuntu 22.04, and in these other machines the chat works fine.

I think there is a workaround: #21255 (comment)

Should be fixed by #21360
