## Summary by CodeRabbit

- **Bug Fixes**
- Enhanced error handling across several modules to ensure smoother
operation when unexpected conditions occur.
- Updated diagnostic and logging mechanisms to provide more robust
system feedback and reduce potential disruptions.
- Improved robustness in the deletion of properties to prevent runtime
errors related to missing keys.
- Added additional exception handling for better analysis of code
entities.
