file_dialog crashes when navigating to folder without read permissions

## Version of Dear PyGui

Version: 1.0.2
Operating System: Windows 10

## My Issue/Question

When using file_dialog and browsing to a folder that the current user does not have access to, dpg will crash.

## To Reproduce

Steps to reproduce the behavior:
1. Open dearpygui.dearpygui.add_file_dialog
2. Navigate to a folder you don't have permissions to
3. Try to get into the folder, dpg will crash

## Expected behavior

Expectation that dpg will not crash when attempting to navigate into folder one doesn't have permissions to. Behavior should be to stay in the parent directory.

## Standalone, minimal, complete and verifiable example

```python
# Here's some code anyone can copy and paste to reproduce your issue
import dearpygui.dearpygui as dpg

dpg.create_context()
dpg.create_viewport()
dpg.setup_dearpygui()

dpg.add_file_dialog(label="File Dialog", show=True)

dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()
```
