2. Use QFileDialog to allow the user to select a file path.
3. Display the selected file path in a QLineEdit widget.
4. Implement a function to save a pandas DataFrame to the file path specified in the QLineEdit.
5. Wrap the saving operation in a try-except block.
6. In the except block, perform no action (pass) to ensure the application does not crash or quit upon error.

# Communication & Style Preferences
Provide clear, executable Python code using PyQt5 and pandas.

## Triggers

- pyqt5 file dialog save excel
- select file path qlineedit
