Hi there! I understand you're having trouble starting Viking Rise. To get a clearer picture—when you say the game won't start, do you mean it doesn’t open at all, or does it get stuck on a loading or splash screen? Also, have you recently updated the game or your Windows OS? Any error messages popping up?

Once I know a bit more, I can guide you better. Meanwhile, here are some initial steps you can try on your Windows 10 setup with WebKit:

1. Restart Your Computer
Sometimes a simple reboot clears temporary glitches affecting apps.

2. Check Your Internet Connection
Viking Rise needs a stable internet connection to initialize. Try browsing other sites or streaming to verify connectivity.

3. Clear Browser Cache
Since you're using a WebKit browser, clearing its cache might help with corrupted files blocking game startup. Usually found under browser settings > Privacy > Clear browsing data (cache and cookies).

4. Disable Browser Extensions
Some extensions might interfere with the game loading. Temporarily disable them and try launching the game again.

5. Update Browser
Ensure your WebKit browser is up to date, as older versions may have compatibility issues.

If you’ve tried these and still can’t get the game going, let me know what happens after these steps. We can dive into more detailed troubleshooting then, including checking any file integrity or account-related settings.

Are you able to give these a try and share what happens next?
