[BUG] Shell commands not executing in Claude Code

I ran into a similar issue.

I started getting this error message:

/opt/homebrew/bin/bash: line 1: /Users/atsaloli/.claude/shell-snapshots/snapshot-bash-a86d2d03.sh: No such file or directory

Here is my status:

 Claude Code Status v1.0.51

...

 System Diagnostics • /doctor
 ⚠  Config mismatch: running npm-global but config says unknown

...

 Model • /model
  L Default (claude-sonnet-4-20250514)

This is very disruptive because I have to start a new session and I will lose all the context I've built up over the past 1-2 days.

I'm running Claude Code on macOS.

I've got a few snapshot files:

$ ls  /Users/atsaloli/.claude/shell-snapshots
snapshot-bash-1752602689429-9c4quv.sh
snapshot-bash-1752607583038-trn39w.sh
snapshot-bash-1752614596408-msimgr.sh
$

They have the same checksum, so I just copied one of them to the filename Claude Code was complaining about, and now Claude Code can run bash commands again:

cp snapshot-bash-1752602689429-9c4quv.sh snapshot-bash-a86d2d03.sh

You can always do claude --continue or claude --resume to resume your session. It's being persisted.

Hi everyone, I'm really sorry for this trouble. It seems we found the limit of our lockfile implementation 😅

We switched to an in-memory implementation of the snapshot in 1.0.54. If you need to see it for debugging purposes, claude will write to a file when you run with --debug

Please let us know if you have any more trouble!

sorry, we had to revert 1.0.54 due to an issue with the in-memory implementation. we are working on this and will try again tomorrow

Ok 1.0.55 is out with the fix. Please let us know how it goes for you.

1.0.56 is the version with the comprehensive fix. please update and report any new issues. thanks for your patience with this one

There is still a problem here, see: https://github.com/anthropics/claude-code/issues/3580#issuecomment-3095956399
