`fish: Job 2, '~/.local/share/claude/versions/…' terminated by signal SIGSEGV (Address boundary error)`

this bug only happened on claude code version 2.1.243, it worked fine on claude code 2.1.241

please fix this issue so i can use the latest claude code version

### What Should Happen?

Claude should launch normally

### Error Messages/Logs

~/.local/share/claude/versions/2.1.243

```

### Steps to Reproduce

### Is this a regression?

Yes, this worked in a previous version

### Last Working Version

2.1.241

### Claude Code Version

(2.1.243) fish: Job 2, 'claude --version' terminated by signal SIGSEGV (Address boundary error)

### Platform

### Operating System

### Terminal/Shell

Other

### Additional Information

i am using the fish shell, not bash

Start by reproducing `claude --version` with version 2.1.243 in the fish shell on Linux, then compare the result with version 2.1.241. Done means Claude Code launches normally without the SIGSEGV error after updating.
