TL;DR

The issue might be resolved by removing duplicate instances of the Claude code, potentially caused by a migration checksum mismatch.

Guidance

  • Investigate the migration process to identify why the checksum mismatch occurred, focusing on the small session mentioned.
  • Check the codebase for any automated scripts or build processes that might be inadvertently duplicating the Claude code instance.
  • Review the feedback.txt file for any specific error messages or clues about the duplication issue.
  • Consider manually removing the duplicate instances as a temporary workaround to verify if the issue is resolved.

Notes

The lack of error messages in the Errors section and the empty JSON array suggests that the issue might not be directly related to a specific error, but rather a configuration or build process problem.

Recommendation

Apply workaround: Manually remove the duplicate instances of the Claude code to verify if the issue is resolved, as the root cause of the migration checksum mismatch is unclear.
