Hi there! I understand that you’re able to use Qobuz fine on your phone, but the app won’t open on your Windows 10 PC using WebKit. Let me help you troubleshoot this so you can get back to enjoying your music.

To start, could you tell me if you’ve noticed any recent updates to the Qobuz app on your PC, or if anything else changed on your system around the time this started happening?

Meanwhile, here’s a step-by-step guide to try:

1. Restart your PC — This can clear temporary glitches that might prevent the app from opening.
2. Run Qobuz as Administrator — Right-click the Qobuz app icon and select "Run as administrator" to see if it starts properly.
3. Reinstall the App — Sometimes files get corrupted: go to Settings > Apps, uninstall Qobuz, then download and install the latest version from the official site.
4. Check for Windows Updates — Ensure your system is up to date by going to Settings > Update & Security > Windows Update.
5. Check if the app process is running already — Sometimes the app might be running in the background but not showing up. Open Task Manager (Ctrl+Shift+Esc), look for any Qobuz processes, and end them before trying to open the app again.

Let me know what you’ve tried and if you see any error messages or behaviors when you attempt to open the app. Based on that, I can help you with more specific steps.

Are you able to try these steps and update me? That will help me guide you better.
