### Explanation of Changes:
1. **Replaced `imp` with `importlib.machinery.SourceFileLoader`:**
   - The `imp` module is deprecated and removed in Python 3.12. The `importlib.machinery.SourceFileLoader` provides a modern alternative for loading Python source files dynamically.
   
2. **Updated the `load_source` call:**
   - The `load_source` function from `imp` is replaced with `SourceFileLoader(...).load_module()` to ensure compatibility with Python 3.12.

3. **No other changes were made:**
   - The rest of the file remains unchanged to minimize modifications while ensuring functionality.

### Next Steps:
After applying this fix, rebuild the package to verify that the issue is resolved. If additional errors occur, they will need to be addressed based on the new build logs.
