[{"error":"Error: NON-FATAL: Lock acquisition failed for /Users/mmaher/.local/share/claude/versions/2.1.108 (expected in multi-process scenarios)\n at vU_ (/$bunfs/root/src/entrypoints/cli.js:2342:2153)\n at Cs6 (/$bunfs/root/src/entrypoints/cli.js:2342:1233)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-04-14T23:22:29.873Z"}]

TL;DR

The issue may be related to a locking mechanism failure, and checking the file system permissions or the lock acquisition process could help resolve the problem.

Guidance

• Investigate the error message "Lock acquisition failed" and its relation to the file path /Users/mmaher/.local/share/claude/versions/2.1.108, which might indicate a file system permission issue or a problem with the locking mechanism.
• Verify that the user has the necessary permissions to access and modify the files in the specified directory.
• Check if there are any other processes or instances of the application that might be holding a lock on the file or directory, causing the acquisition failure.
• Consider checking the application's documentation or source code to understand the locking mechanism and how it's used in multi-process scenarios.

Example

No code snippet is provided as it's not clearly supported by the issue, and generating code might introduce unnecessary complexity.

Notes

The issue seems to be related to a specific version (2.1.108) of the application, and the error message mentions a "multi-process scenario", which might be relevant to the problem. However, without more information about the application's architecture and the locking mechanism, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: The user may need to manually remove any existing locks or modify the file system permissions to resolve the issue, as there is no clear indication of a fixed version available.
