fix: Enhance loading functions to handle non-existent directories

- Added checks in various loading functions to ignore processing if the respective directories do not exist, improving error handling and preventing unnecessary operations.
- Updated the Load function signature to return warnings alongside errors, allowing for better feedback on loading issues across different components.
