Cowork bridge registration stuck in 409 loop — ghost environment can't be cleared

Environment

• Claude Desktop v1.2581.0
• macOS on Apple Silicon

Problem

Cowork / Dispatch got stuck in a bridge registration conflict loop and could not recover cleanly.

Symptoms

• Repeated Cowork bridge registration failures
• Claude reported that an agent was already registered on the machine
• Restarting the app alone did not clear the condition

Local resolution

Resolved locally after fully quitting Claude Desktop, clearing persisted local Cowork bridge/session state, and relaunching the app.

Notes

Closing this because it is no longer reproducible on my machine. There may still be a broader stale-environment / bridge-recovery issue related to existing reports.
