[{"error":"Error: NON-FATAL: Lock acquisition failed for /Users/byronluk/.local/share/claude/versions/2.1.118 (expected in multi-process scenarios)\n at ai_ (/$bunfs/root/src/entrypoints/cli.js:2756:2177)\n at IK8 (/$bunfs/root/src/entrypoints/cli.js:2756:1257)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-04-23T01:05:31.523Z"}]

TL;DR

The issue may be related to a lock acquisition failure, and removing the lock file could potentially resolve the rewind issue.

Guidance

• The error message suggests a lock acquisition failure, which might be causing the rewind functionality to get stuck. Investigating the lock file location /Users/byronluk/.local/share/claude/versions/2.1.118 could provide more insights.
• Try removing the lock file (if it exists) to see if it resolves the issue. This can be done by running a command like rm /Users/byronluk/.local/share/claude/versions/2.1.118 in the terminal.
• If removing the lock file does not work, try checking the file system permissions for the lock file location to ensure that the application has the necessary permissions to acquire the lock.
• Consider checking for any other error messages or logs that might indicate a more underlying issue with the application.

Example

No code snippet is provided as it is not clearly supported by the issue.

Notes

The provided solution is based on the error message indicating a lock acquisition failure. However, without more information about the application's internal workings, it's difficult to provide a more definitive solution. The suggested steps are intended to be exploratory and may not fully resolve the issue.

Recommendation

Apply workaround: Removing the lock file could potentially resolve the rewind issue, but it's essential to investigate the root cause to prevent similar issues in the future.
