Agent Mode fails when editing files on insert_edit_into_file with args

[NateRadebaugh]

• VS Code Version: 1.101.2
• OS Version: Windows 11 Enterprise 23H2
• GitHub Copilot: github.copilot 1.336.0
• GitHub Copilot Chat: github.copilot-chat 0.28.2

Steps to Reproduce:

1. Ask agent to create a file: success
2. Ask agent to change the file contents: error

Reviewing the "GitHub Copilot Chat" logs show the following:

I've tried:

• Uninstalling copilot extensions
• Log out/in
• Run vscode as administrator

Other copilot functionality works and I'm already successfully logged in, but the insert_edit_into_file is failing with:
