Hi there! I see your Stelo app won’t open, and I want to help get that sorted out for you. To better assist, could you tell me if the app just doesn’t respond at all when you tap it, or does it start to open and then close quickly? Also, have you tried any steps so far like restarting your phone or closing and reopening the app?

Meanwhile, here are some simple steps we can start with to troubleshoot:

1. Force close and restart the app: Since you're on Windows with a WebKit browser, if you’re using the Stelo app in any browser context, try closing the entire browser and reopening it. If it’s a desktop app, use Task Manager (Ctrl + Shift + Esc), find Stelo, end task, and try opening it again.

2. Restart your computer: Sometimes a simple reboot can clear temporary glitches and allow the app to open properly.

3. Check for updates: Ensure your Stelo app (or browser) is fully updated. Outdated apps may fail to launch or behave unexpectedly.

4. Clear cache or temporary data: For browser-based usage, clearing your browser cache might help. You can do this from browser settings.

5. Check network connection: Make sure your computer is connected to the internet, as Stelo may require connectivity to launch properly.

If these don’t help or you’ve already tried some, let me know what you’ve done or if there's any error message showing up. I’m here to guide you through the next steps!
