[BUG] UI State Race Condition / App freeze during overlapping interactive requests

What's Wrong?

The Claude Desktop app (and Claude Code CLI) crashes or freezes, displaying a "_Claude will return soon_" service disruption screen. This happens specifically when a new request is sent while the previous request is still in an interactive state (waiting for an option selection). It appears to be a race condition between the UI state update and new input handling.

What Should Happen?

The app should either: 1) Block or queue new input until the current interactive selection is rendered/resolved, or 2) Gracefully cancel the previous pending selection if a new request is initiated, without crashing the session.

Error Messages/Logs

Message displayed: "Claude will return soon. Claude is currently experiencing a temporary service disruption."

Steps to Reproduce

1. Initiate a request that triggers an interactive response (e.g., asking Claude to choose between multiple files or options).
2. Before the selection options are rendered on the screen, immediately send a new request or command.
3. The application fails to handle the concurrent states and displays the "Claude will return soon" error screen.

Note: This issue seems specific to the timing of the input. If I wait for the options to appear, the crash does not occur. Attached is the screenshot of the error
