Subject: [PATCH 1/2] Resolved crashing nodes caused by `FileNotFoundError`
 during directory traversal

- Implemented a `try-except` block in the `recursive_search` function to handle `FileNotFoundError` gracefully.
- When encountering a file or directory path that cannot be accessed (causing `FileNotFoundError`), the code now logs a warning and skips processing for that specific path instead of crashing the node (CheckpointLoaderSimple was usually the first to break). This allows the rest of the directory traversal to proceed without interruption.
