[BUG] Can't submit a prompt on Claude Code on deskptop app for Windows

What's Wrong?

In the Claude Desktop app, the Code tab input field no longer converts the microphone icon into a send (arrow) button when text is typed. As a result, there is no way to submit a prompt using the keyboard or mouse.

Additionally, pressing Enter shifts focus to the "Select folder" button instead of sending the message.

The Chat tab works correctly — the microphone icon does convert to a send arrow when text is entered.

Actual Behavior
The microphone icon stays as-is. Pressing Enter moves focus to "Select folder". There is no way to send a message in the Code tab.

Environment

• Platform: Claude Desktop App (Windows)
• Tab: Code
• This worked before the recent update
• OS: Windows 11 version 25H2

What Should Happen?

The microphone icon should convert to a send (arrow) button when text is present, as it does in the Chat tab. Pressing Enter should send the message.
