Hi there! I understand that when you try to open the Property Brothers Home Design app on your Windows device, it just shows a black screen instead of loading the game. Let's work through a few things to get this sorted out.

First, could you tell me:
- Have you tried restarting your device since this started happening?
- Is your internet connection stable and working fine for other apps or websites?
- Do you have the latest version of the app installed?
- Have you noticed if this problem started after an update or some change?

While I wait for that info, here are some quick steps you can try to fix the black screen issue on your Windows 10 device:

1. Restart the app and your device: Close the app completely, then restart your Windows computer. This can clear temporary glitches.

2. Check app permissions: Make sure the app has permission to access graphics resources or network if applicable.

3. Update graphics drivers: On Windows, outdated or corrupted graphics drivers can cause rendering issues like a black screen. You can update your graphics driver via:
- Open Device Manager (press Windows + X, then select Device Manager)
- Expand Display adapters
- Right-click your graphics card and select Update driver > Search automatically

4. Clear app cache/data: If the app stores corrupt data, it can cause loading issues. To clear cache:
- Go to Settings > Apps > Property Brothers Home Design
- Click Advanced options > Reset (this will clear app data, but won't uninstall the app)

5. Run the app as Administrator: Right-click the app shortcut, choose Run as administrator. Sometimes elevated permissions help.

6. Check for Windows updates: Make sure your OS is fully updated, as some updates fix compatibility issues.

If after these steps the black screen still appears, we might need to look deeper into app-specific bugs or server-side problems. At that point, contacting the Property Brothers support team along with a screenshot of the black screen might be necessary.

Give these a try and let me know where you get to or if you notice anything different. We'll figure this out together! Are you comfortable following these steps so far?
