Hey there! Sorry to hear the Rick and Morty app keeps crashing on your iPhone, and I understand losing your data after uninstalling isn’t fun at all. Just to get a clear picture — are you using any account or cloud sync with the app? Sometimes data (like game progress) is saved to the cloud or linked to a user account, which can help restore it after reinstalling.

Meanwhile, let me walk you through some steps that might help fix the crashing, and possibly safeguard your data moving forward:

1. Check for Updates
Make sure your iOS (which I see is 18.5) and the Rick and Morty app are both updated to the latest versions. Developers often release fixes for crashes.

2. Enable Data Sync (If Available)
Within the app’s settings (if it opens long enough), look for a “Sync App Data” or “Cloud Save” option. Turning this on helps keep your data saved remotely.

3. Clear Cache and Free Up Space
On iOS, you can free up space by offloading unused apps or clearing Safari’s cache (Settings > Safari > Clear History and Website Data). Sometimes low storage can cause app instability.

4. Reinstall and Sign in
Since uninstalling caused data loss last time, once you reinstall the app, sign in with the same account (if the app uses one). This might restore your previous data.

5. Restart Your iPhone
A simple restart after reinstalling the app can sometimes clear temporary glitches causing crashes.

If the problem persists despite these, the app itself might have specific issues or server problems causing the crashes and data loss. I can check for any reports on this or guide you toward official support if needed.

Just to be thorough, have you tried any of these steps already? And if so, which ones? That way I can tailor the help better for you.
