Hi there! I’m Emily, happy to help you get your Burger King app up and running on your Android 14 device. To start, could you tell me a bit more about what happens when you try to open the app? For example, does it crash immediately, get stuck on a loading screen, show an error message, or just not respond at all?

Once I know a bit more, I can guide you through some targeted steps to fix it. Meanwhile, here's a general approach we can try:

1. Restart your phone: Sometimes a simple reboot clears temporary glitches.
2. Force Stop the app: Go to Settings > Apps > Burger King > Force Stop, then try opening it again.
3. Clear Cache and Data: In the same app settings, clear cache first. If that doesn’t work, clear data (note this will log you out and reset the app).
4. Check for App Updates: Open Google Play Store, search for Burger King, and update if available.
5. Reinstall the App: Uninstall Burger King, then reinstall the latest version from Google Play.

If the app still won't start, there could be a connection issue, or a bug in the app version itself, in which case we can explore more advanced fixes.

Let me know what you've tried so far and exactly what happens when you start the app! That way, I can tailor the solution better for you.
