Hi! I understand your Angry Birds Journey app keeps crashing on your iPhone SE 2020 even though both your iOS (18.7) and app are up to date, and you've already tried reinstalling it several times. Let's dig a little deeper to get to the bottom of this.

To start, could you tell me:
- Does the app crash immediately upon opening, during gameplay, or at a specific point (like loading or after a level)?
- Are you connected to a stable internet connection when playing?
- Do you use Game Center with your Angry Birds account?

Meanwhile, here are some steps we can try that often resolve crashing issues on iPhones:

1. Force Close and Restart: Swipe up from the bottom (or double-click Home for iPhone SE 2020) to see open apps, then swipe Angry Birds Journey off the screen to close it. Open it again to check if it works.

2. Restart Your iPhone: Hold the side button and volume up button until you see “slide to power off,” then turn it off. Wait a moment, then turn it back on and try the app again. A fresh start can clear temporary glitches.

3. Sign Out of Game Center: Since the game is tied to Game Center, signing out and back in can fix account sync problems:
- Open Settings on your iPhone.
- Tap your Apple ID at the top.
- Select Game Center.
- Tap your Apple ID, then tap Sign Out.
- Restart your phone.
- Sign back into Game Center and open the game.

4. Check for App Data Conflicts: If you use multiple Apple devices or switched phones recently, corrupted save data can cause crashes. After signing out of Game Center, uninstall the app again, restart your phone, and then install the app fresh before signing back in.

5. Free Up Storage: Low device storage can cause apps to crash. Go to Settings > General > iPhone Storage and check if you have at least a few hundred MB free.

If none of these clear it up, we may want to check if there is a server-side issue or a known conflict with your iOS version, but let’s start with these to narrow it down.

Let me know how these steps go or if you notice any specific patterns when it crashes!
