VSCode crashes when Copilot agent is allowed to fetch content from pdg.lbl.gov

[MohamedElashri]

Describe the bug

If the agent tried to use the internet search and came up with the particle data table websit and once you allow it then it will crash the whole VSCode

Affected version

0.37.9

Steps to reproduce the behavior

1. Open GitHub Copilot Chat in VSCode (agent mode)
2. Ask a question that prompts the agent to search the web (e.g., a particle physics query like explicilty asking about muon mass in the pdg table)
3. The agent attempts to fetch content from https://pdg.lbl.gov/
4. A permission prompt appears asking to allow the internet search — click Allow
5. VSCod1e crashes immediately after allowing access

Expected behavior

The agent should successfully fetch and parse content from https://pdg.lbl.gov/, returning relevant results within the Copilot Chat panel, without any crash or instability in the VSCode window.
