Title

fix: add exception handling for empty or corrupt .env file

Description

This PR addresses the issue of unhandled exceptions when loading environment variables from a .env file. The application previously crashed when encountering issues such as an empty file, incorrect UTF encoding, malformed content, or a missing file. This change introduces exception handling to gracefully manage these scenarios, providing meaningful error messages and preventing application crashes.

Fixes # (issue number)

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Refactor (does not change functionality, e.g. code style improvements, linting)
• Documentation update

How Has This Been Tested?

The changes have been tested by simulating various .env file issues:

1. An empty .env file
2. Incorrect UTF encoding
3. Malformed content
4. Missing .env file

The application was run in each scenario to ensure that it no longer crashes and that appropriate error messages are logged.
