Hi there! I see you've been having trouble opening the Rummikub app for the past 48 hours. Let’s get to the bottom of this together.

To start, could you please confirm a couple of things for me?
- Are you trying to open Rummikub on your Windows device via a web browser (WebKit-based, like Safari or another)?
- Do you get any error messages when you try to open the app?
- Have you tried clearing your browser cache or using a different browser?
- Are you running the latest version of your browser and Windows 10 OS updates?

While waiting for your answer, here are some straightforward steps that can often fix app launch issues on Windows browsers:

1. Clear your browser cache and cookies: Sometimes old data can cause loading issues.
2. Check for browser updates: Ensure your WebKit-based browser is updated to the latest version.
3. Try a different browser: If possible, open Rummikub in Chrome, Firefox, or Edge to see if it opens there.
4. Disable browser extensions: Sometimes ad blockers or security extensions block scripts needed for the app.
5. Restart your PC: This can clear temporary glitches affecting app launch.

If the app still won’t open after these steps, it could be related to a network or server issue (since others have reported similar problems requiring updates or troubleshooting)1 2.

Please let me know what you’ve already tried and the answers to my questions, and I’ll guide you further!
