What's Wrong?

Bug Report

Version: 2.1.72
OS: Ubuntu Linux

Description

Claude Code crashes immediately when executing commands in v2.1.72.
The bundled rg (ripgrep) binary is no longer being dispatched correctly —
instead of running ripgrep, the binary treats the call as a Claude CLI command.

Steps to Reproduce

Run any command in Claude Code v2.1.72 that triggers a file scan.

Observed Behavior

Running the bundled binary as rg returns:

error: unknown option '--no-config'
(Did you mean --mcp-config?)
Exit code: 1

This causes a cascade of all subprocesses exiting with code 1 and terminates Claude Code.

strace Evidence

execve("/home/user/.local/share/claude/versions/2.1.72", ["rg", "--no-config", "--files", ...])
exit_group(1)

Fix

Downgrading to v2.1.71 resolves the issue immediately.

What Should Happen?

It shouldn't crash
