TL;DR

The issue might be resolved by reverting to the previous version of Claude Code that was working 2 hours ago, as the problem started after the latest update.

Guidance

  • Try reverting to the previous version of Claude Code to see if the issue persists, which can help confirm if the latest update is the cause.
  • Since the issue is reported as a regression and the previous version was working, comparing the changes between the two versions might provide insight into what's causing the crash.
  • As the crash occurs without any error messages, monitoring system resources (e.g., CPU, memory) during the startup of Claude Code might provide clues about what's leading to the freeze.
  • Consider reaching out to the development team or community for further assistance, as this issue seems to be directly related to the update and might require specific knowledge about the changes made.

Notes

The lack of error messages or logs makes it challenging to pinpoint the exact cause. The fact that it's a regression and happens consistently after the update suggests the issue is likely related to changes in the latest version of Claude Code.

Recommendation

Apply workaround: Revert to the previous version of Claude Code until a fix for the latest version is available, as it's confirmed to have worked in the past and the current version causes a critical issue.
