Hi there! I understand your video poker games in the DoubleDown app are not loading on your Windows device using WebKit. Let's work through this together to get you back to playing.

First, just to confirm:
- Are you using the DoubleDown app or playing through a browser?
- Have you tried restarting the app or your browser yet?
- Have you cleared your browser cache recently?

Usually, some common steps resolve loading issues like this. Here's a step-by-step you can try on your Windows 10 system using WebKit browser:

1. Restart your browser: Close all browser windows completely and then reopen the browser. Sometimes the game just needs a fresh start.

2. Clear browser cache and cookies: Cached files can cause loading problems if corrupted or outdated. Here's how:
- Open your browser settings.
- Find the privacy or browsing data section.
- Select the option to clear cache and cookies (make sure to focus on cached images/files and cookies).
- Restart the browser after clearing.

3. Check for browser updates: Ensure your WebKit browser is fully updated, as older versions might have compatibility issues.

4. Disable any browser extensions: Sometimes extensions can interfere with loading. Try disabling them temporarily and reload the game.

If you are using the app or a hybrid app on Windows (like through an emulator or Microsoft Store), try this:

- Close the app completely.
- Go to Settings > Apps > DoubleDown.
- Clear the app cache and data (this is similar to clearing browser cache but for the app).
- Restart the app and see if the poker game loads.

If none of these steps work, please let me know if you notice any error messages or loading behavior (e.g., spinning wheel, blank screen) and if your internet connection is stable.

Does this sound like a good place to start? Let me know how it goes or if you have already tried some of these steps!
