Hi! I understand that your Prisma3D app keeps crashing on your iPhone running iOS 18.7.1, and you've confirmed that storage space is not the issue. Let's work together to fix this.

To get started, may I ask:
- When exactly does the app crash? (e.g., on startup, when importing a project, applying textures, etc.)
- Have you recently updated the app or your iOS version before these crashes began?
- Have you tried restarting your device or reinstalling the app?

Meanwhile, here’s a structured plan you can try:

1. Force Close and Relaunch the App
- Double-tap the Home button or swipe up from the bottom (depending on your iPhone model) to open the app switcher.
- Swipe up on Prisma3D to close it completely.
- Relaunch the app and see if it still crashes.

2. Check for App Updates
- Go to the App Store and check if there is any update available for Prisma3D. Developers often release fixes for stability issues.

3. Restart Your iPhone
- Power off your iPhone, wait 30 seconds, then power it back on. This clears temporary glitches.

4. Clear Prisma3D Cache (if applicable)
- Sometimes app caches can cause crashes. While iOS apps don’t have a built-in cache clear option, reinstalling resets this.

5. Reinstall Prisma3D
- Press and hold the Prisma3D icon until you see “Remove App”. Tap it to uninstall.
- Reinstall the app from the App Store.

6. Disable Background Apps
- Running multiple apps in the background might conflict. Close other apps fully to free up resources.

7. Check Permissions
- Go to Settings > Prisma3D and verify all necessary permissions are enabled (Photos, Camera, etc.).

8. Examine Project Files
- If the crash happens during specific tasks like importing projects or applying textures, try saving your work first. Then retry applying textures because there are reports of crashing when applying textures, but reopening the project allows retrying without crashes2.

If after these steps the crashing persists, it might be linked to a bug specific to the app or iOS version interaction. The latest support discussions sometimes highlight reinstalling or waiting for app updates as solutions1 4.

Let me know which steps you’ve tried or if you notice specific actions triggering the crash. That will help me guide you further! Are you satisfied with this solution so far?
