claude-code - 💡(How to fix) Fix [Bug] Control+C does not interrupt vim mode editor [1 comments, 2 participants]

[{"error":"Error: NON-FATAL: Lock acquisition failed for /Users/david/.local/share/claude/versions/2.1.119 (expected in multi-process scenarios)\n at mH6 (/$bunfs/root/src/entrypoints/cli.js:2736:2177)\n at E$8 (/$bunfs/root/src/entrypoints/cli.js:2736:1257)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-04-24T06:26:27.962Z"}]

TL;DR

The issue may be related to the vim mode in claude, which is not interrupting when Control+C is pressed, and a potential workaround could be to exit vim mode before attempting to interrupt.

Guidance

• Investigate the relationship between vim mode and interrupt handling in claude to understand why Control+C is not working as expected.
• Check if there are any configuration options or settings in claude that can be adjusted to enable interrupt handling while in vim mode.
• Consider filing a new issue or reopening the related issue #38328 to further discuss and resolve the problem.
• Review the error message provided to see if it offers any clues about the lock acquisition failure and its potential impact on interrupt handling.

Notes

The provided error message seems unrelated to the interrupt handling issue, but it may indicate a broader problem with claude's locking mechanism.

Recommendation

Apply workaround: Given the lack of information about a fixed version, the best course of action is to apply a workaround, such as exiting vim mode before attempting to interrupt, until a more permanent solution is found.
