Hi there! I understand that your Texas Hunt & Fish app crashes immediately when you open it on your iPhone 7 running iOS 15.8.4. Let’s see how we can get this sorted out.

To start, have you tried any troubleshooting steps yet? If so, could you let me know which ones? This helps me avoid repeating what you've already attempted.

Assuming you haven’t, here’s a straightforward step-by-step approach we can try:

1. Force Close the App
- Double press the Home button to see your recent apps.
- Find the Texas Hunt & Fish app and swipe it up off the screen to close it completely.
- Then try reopening it.

2. Restart Your iPhone
- Press and hold the side power button until the slider appears.
- Slide to power off.
- After the device turns off, press and hold the power button until the Apple logo appears.
- Open the app again.

3. Check for Updates
- Open the App Store, tap on your profile icon, then scroll to see if there are updates available for Texas Hunt & Fish.
- If yes, update the app to the latest version.

4. Delete and Reinstall the App
- Touch and hold the Texas Hunt & Fish app icon, tap “Delete App”, and confirm.
- Go to the App Store, search for the app, and reinstall it.

5. Check iOS Version Compatibility
- Since you're on iOS 15.8.4, verify if the app requires a newer iOS version. Sometimes apps crash if they aren’t fully compatible with the installed OS.

If you’ve done some of these steps already or if the app still crashes after trying these, let me know. We can then look into deeper issues like app permissions, storage space, or even account-related problems.

Does this help get the app running better?
