Hi! I understand your SP Camera app won’t open after the latest iOS update to 18.6. Let's work together to get this sorted out. Before we dive into detailed steps, could you tell me if the app crashes immediately when you try to open it, or does it just not respond at all? Also, have you tried any troubleshooting steps so far?

In the meantime, here are some common and effective steps we can try:

1. Restart Your Mac
Sometimes, a simple restart can clear up temporary glitches after an update.

2. Check for SP Camera App Updates
Open the App Store, go to the Updates tab, and see if there’s an update available for SP Camera. The update might include fixes for compatibility with iOS 18.6.

3. Review Camera Permissions
Since iOS updates often reset or change privacy settings, open your Mac’s System Preferences > Security & Privacy > Privacy tab > Camera, and ensure SP Camera has permission to use the camera.

4. Force Quit and Relaunch the App
Press Command + Option + Escape to open the Force Quit window, select SP Camera if it’s listed, and force quit it. Then try opening it again.

5. Reinstall the App
Delete SP Camera from your Mac, then reinstall it from the App Store. This can fix corrupted app files.

6. Check for macOS Updates
Ensure that your Mac is fully updated as well under System Preferences > Software Update.

If these steps don’t resolve the problem, there might be a deeper compatibility issue with the iOS 18.6 update. In that case, I can assist you with:

- Checking for detailed logs or error messages from the app.
- Looking into specific app conflicts or preference files that might need resetting.
- Guiding you through resetting system settings related to the camera.

Could you please let me know how it behaves exactly and which steps, if any, you’ve tried already? That way, I’ll tailor the next advice just for your case.
