What's Wrong?

Claude code doesn't load. The VSCode app reports Claude Code process exited with code 3221225477. The CLI usually returns without displaying anything, but sometimes asks me what theme I'd like to use before crashing before accepting any input.

What Should Happen?

Claude Code should successfully load.
