Fix SyntaxError: duplicate except blocks and indentation

🔧 **Syntax Error Fix**:

1. **Duplicate Except Blocks**:
   - Removed duplicate except Exception as e blocks
   - Fixed improper nesting of exception handlers

2. **Indentation Issues**:
   - Corrected indentation for exception handling
   - Fixed try-except block structure

3. **Code Structure**:
   - Cleaned up ModelPatcher analysis exception handling
   - Removed redundant error logging
   - Simplified exception flow

The SyntaxError on line 433 has been resolved and the code
should now load properly in ComfyUI.
