Agent Hangs on Complex Prompts, Becomes Unresponsive

Bug Description
Subject: Agent freezes and becomes unresponsive on complex prompts

Environment:

• Operating Systems (Confirmed): macOS, Ubuntu Desktop, WSL

Bug Description:
The agent has recently started becoming unresponsive when given any prompt that requires a non-trivial amount of thought or planning. When this occurs, the agent might indicate it is
"Thinking..." or "updating tools," but it never actually performs an action or returns a response. It simply hangs indefinitely.

This issue is not related to a specific connection method and has been confirmed to happen on both macOS and Ubuntu Desktop environments. Simple, direct commands work as expected, but
any task requiring deeper processing now fails.

Troubleshooting Steps Taken:

• Logging out and back into the account.
• Re-installing the agent/tool.

These actions did not solve the issue.

Steps to Reproduce:

1. On a supported OS (macOS or Ubuntu Desktop), launch the agent.
2. Provide a prompt that requires complex processing (e.g., "Analyze this code snippet for potential bugs," or "Draft a detailed project plan for a new web application").
3. Observe that the agent indicates it is processing but then freezes and never delivers a response.
