Hi there! I understand that the Star & Planet Finder app crashes immediately when you try to open it on your Windows device using the WebKit browser. Let's work together to get this sorted out.

To start, could you let me know a bit more about when the app started crashing? Also, have you recently updated the app or your Windows version? Additionally, have you tried any fixes already, like restarting the device or reinstalling the app?

While I wait for your reply, here are some steps you can try with your current setup:

1. Restart your device: Sometimes a simple restart can clear any temporary glitches.

2. Check for app updates: Even though you’re on Windows with a WebKit browser, make sure you have the latest version of the Star & Planet Finder app or web app.

3. Clear browser cache: Since your device uses WebKit, clearing the browser cache might help. You can do this from the browser's settings under privacy or history.

4. Check your internet connection: Try switching to a different Wi-Fi network or using a wired connection if possible. Some users have found that network issues can cause crashes.

5. Time and date settings: Ensure your computer’s time zone and date/time are set correctly under Windows Settings > Time & Language > Date & Time.

If you’ve tried all the above and the app still crashes instantly, the next steps could involve checking for any error messages on launch that might help diagnose further or seeing if there is an update or patch from the app developers addressing known crashes.

Could you please tell me if you notice any error messages or if the crash happens right as you open the app? Also, let me know if the app was working fine before or if this started after an update.

I’m here to help!
