Wrap the file reading operations within a `try...except` block. Specifically, catch `FileNotFoundError` if the file doesn't exist and `IOError` (or its subclasses like `PermissionError`) for other file-related issues. Inside the `except` block, log the error, provide a user-friendly message to the user, and potentially attempt to open a different file or exit gracefully. Also use `with open(...)` to ensure the file is properly closed even if an error occurs.
