TL;DR

The issue is likely related to a database file access problem, and checking the database file's location and permissions may provide a workaround.

Guidance

  • Verify the database file exists and is accessible at the expected location.
  • Check the file system permissions to ensure the Codex App has read and write access to the database file.
  • Consider reinstalling the Codex App or resetting its configuration to default settings to potentially resolve any corrupted database file issues.

Notes

The provided information does not include specific details about the database file or its location, so further investigation is needed to determine the root cause.

Recommendation

Apply workaround: Checking the database file's location and permissions is a safe and reasonable first step to try and resolve the issue without making any significant changes to the system or app configuration.
