Hey, thanks for the report. Let’s go through this step by step:

  1. Error check:

    • Open Help > Toggle Developer Tools > Console
    • Do you see any red error messages when the extension freezes? Please share a screenshot

  2. Extension conflict check:

    • Disable all other extensions except Claude Code
    • Restart Cursor and check if Claude Code works now
    • Did that help?

  3. MCP servers:

    • Do you have any MCP servers in Cursor Settings > Features > MCP?
    • If yes, temporarily disable them to see if they cause conflicts

  4. Extension Monitor:

    • Enable Settings > Application > Experimental > Extension Monitor Enabled
    • Run Cmd+Shift+P > Developer: Open Extension Monitor
    • Does the Claude Code extension show high CPU/memory usage or errors?

Please share the results of these checks.
