TL;DR

The issue with Claude Code requiring a login every time it's run, despite previous logins, may be related to authentication or session management issues, and checking the lock acquisition failure and Axios errors could provide more insight.

Guidance

• Investigate the "Lock acquisition failed" error for /Users/vldk/.local/share/claude/versions/2.1.116 to understand if it's related to multi-process scenarios or file system permissions.
• Review the Axios errors with status codes 400 and 401, which indicate bad requests and unauthorized access, respectively, to see if there's an issue with the request payload or authentication tokens.
• Check the authentication mechanism used by Claude Code to see if there's an issue with session persistence or token renewal.
• Consider clearing the local storage or cache for Claude Code to see if it resolves the issue, but be cautious of losing any important data.

Example

No specific code example can be provided without more context, but checking the cli.js file at the mentioned lines (e.g., 2752:2177, 110:1194) might give clues about the error handling and authentication logic.

Notes

The provided error messages and stack traces suggest issues with both local file system access and remote API calls, making it challenging to pinpoint the exact cause without more information about the Claude Code application and its environment.

Recommendation

Apply a workaround by checking the authentication tokens and session management to ensure they are correctly set and persisted between runs, as the root cause seems to be related to authentication or authorization issues.
