What's Wrong?

System Information:
Claude Version = 1.0.58 (Claude Code)
NAME="Ubuntu"
VERSION="20.04.6 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04.6 LTS"
VERSION_ID="20.04"

When I start up Claude Code I periodically run into issues with shell snapshots.

This happens after 15-20 minutes of usage, and doesn't go away until I restart. It happens much more frequently when I am running two Claude Code instances on the same machine (each running in a completely separate repo &directory).

What Should Happen?

Claude should be able to find the snapshot and run bash commands.

Error Messages/Logs

Task(Update Lambda IAM policy)
  ⎿  Bash(my-command-goes-here)
     Waiting…
     Error: /bin/bash: 
     /home/username-goes-here/.claude/shell-snapshots/snapshot-bash-1760151834754-yf0jld.sh:
      No such file or directory

Steps to Reproduce

1) Start up a Claude instance (instance-1)
npm install -g @anthropic-ai/claude-code
claude

2) Ask instance-1 to do something - let it run
repeat ten times: create a text file with 42 zeroes named "foo_bar.txt", sleep for a minute, overwrite the text file with the exact same contents

3) Open a new terminal, change to a separate directory, start up Claude instance (instance-2)
cd ../new-dir-name/
claude

4) Tell instance-2 to do something else
repeat ten times: create a text file with a randomly generated dad joke named "dad_jokes.txt", sleep for a minute, overwrite the text file with another randomly generated dad joke

5) Wait for the errors to start showing up in either instance. Usually it will be the second instance (instance-2 here).
