What's Wrong?

Every time I ask Claude Code to access my computer's folders through the desktop app, the session crashes with exit code 3221225477.
Environment:

• OS: Windows 11 Home (ARM64)
• App version: 1.12603.1
• Architecture: arm64
• Node version: 24.16.0
• What happens:

The Claude Code process exits with code 3221225477 immediately when attempting to access the local filesystem. Also, when I try to do big tasks. The desktop app shows the session as failed. The error appears in the logs as: Error: Claude Code process exited with code 3221225477

What Should Happen?

Claude Code should be able to access folders without crashing.
