Hi! I understand that when you open the SanDisk Memory Zone app on your Windows 10 device, the splash screen appears briefly and then the app closes or disappears without starting fully. Let me help you get it working properly.

To clarify before we start:
- Are you seeing any error message at all, or does it simply close after the splash screen?
- Did this issue start after a recent update or installation?
- Have you tried reinstalling the app already?

In the meantime, here’s a step-by-step checklist to try:

1. Restart your PC: Sometimes a simple restart clears temporary glitches.

2. Run as Administrator: Right-click the SanDisk Memory Zone app icon and select "Run as administrator" to ensure it has full permissions.

3. Temporarily Disable Antivirus/Firewall: Sometimes security software blocks apps from launching fully. Try temporarily disabling them and then start the app.

4. Check for App Updates: Make sure your app is the latest version by downloading it again from the official SanDisk website.

5. Reinstall the App:
- Uninstall the SanDisk Memory Zone app completely via Settings > Apps.
- Restart your PC.
- Download and install the latest version.

6. Check Windows Compatibility Settings:
- Right-click the app > Properties > Compatibility tab.
- Try running the app in compatibility mode for Windows 8.

7. Check Background Processes: Sometimes leftover app processes cause startup issues.
- Open Task Manager (Ctrl + Shift + Esc).
- Look for any SanDisk Memory Zone processes and end them.
- Then try restarting the app.

If it still fails after these steps, the issue could be deeper with app permissions or conflicts on your system. In that case, I’ll guide you through advanced logs or configuration checks, or we can consider contacting SanDisk support directly.

Let me know which steps you’ve tried so far and if you noticed anything specific when the splash screen disappears!
