Root Cause

Note: unfortunately, I'm unable to provide a crash dump from a session in which this has occurred, because I cannot run /feedback after this bug happens. However, I confirmed that resuming this exact session in iTerm or Cursor would trigger the failure.

RAW_BUFFERClick to expand / collapse

Bug Description In this claude version, hitting escape twice to go back often crashes the UI unrecoverably. I can still scroll up and down, but I can no longer interact and have to forcibly quit claude. This happens both in the Cursor integrated terminal and in iTerm.

extent analysis

TL;DR

The issue might be related to a lock acquisition failure or a missing tool, and a potential workaround could be to check the lock file or tool configuration.

Guidance

  • Investigate the lock acquisition failure error and check if the file /Users/teoman/.local/share/claude/versions/2.1.119 is accessible and not locked by another process.
  • Verify if the Tool TeamDelete is properly configured and installed, as the error suggests it's not found.
  • Try to reproduce the issue in a clean environment to isolate the problem.
  • Check the claude documentation for any known issues or configuration recommendations related to lock acquisition and tool management.

Example

No code snippet is provided as the issue seems to be related to configuration or environment rather than code.

Notes

The lack of a crash dump and the specific error messages suggest that the issue might be related to the environment or configuration rather than a code bug. Further investigation is needed to determine the root cause.

Recommendation

Apply workaround: Check the lock file and tool configuration to see if it resolves the issue, as the error messages suggest a potential problem with lock acquisition or tool management.
