CodeTrial crashes when starting an interview on macOS 26 arm64

[MorganHo001]

Description

CodeTrial crashes when starting a mock interview on macOS 26 with Apple Silicon.

CodeTrial starts normally and the web interface is accessible at http://127.0.0.1:3000. However, after starting an interview and dispatching the interview room, the process terminates with an NSInvalidArgumentException.

Environment

• macOS: 26.6.2
• Architecture: arm64 (Apple Silicon)
• CodeTrial binary: codetrial-aarch64-apple-darwin

Steps to reproduce

1. Run codetrial-aarch64-apple-darwin.
2. Open http://127.0.0.1:3000 in a browser.
3. Start a mock interview.
4. Wait for CodeTrial to dispatch the interview room.
5. The CodeTrial process crashes immediately after the room is dispatched.

Actual behavior

The terminal shows:

codetrial dispatch room=interview-0vbuf7wc

*** Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: '+[NSString stringForAbslStringView:]: unrecognized selector sent to class 0x1f612e100'

libc++abi: terminating due to uncaught exception of type NSException
zsh: abort codetrial-aarch64-apple-darwin

Expected behavior

The interview should start normally after the room is dispatched instead of terminating the CodeTrial process.
