[BUG] [Claude Desktop] Hamburger menu non-interactive before login on Windows — blocks third-party inference setup

• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

On Windows, the hamburger menu (top-left) in Claude Desktop is visible but completely unresponsive before logging in. This blocks the documented third-party inference setup flow, which instructs users to navigate to Help → Troubleshooting → Enable Developer mode → Developer → Configure third-party inference without logging in.

The same flow works correctly on macOS — the menu bar is fully interactive before login.

What Should Happen?

The hamburger menu should be interactive before login, allowing access to Help → Troubleshooting → Enable Developer mode, as described in the Cowork third-party setup documentation.
