Hi there! I see that your Test'em All app crashes immediately after you open it on your iPhone running iOS 18.5.0. Let me help you get this sorted out.

To start, could you let me know if this started happening after any recent update to the app or your phone's iOS? Also, have you tried closing the app fully and restarting it, or rebooting your iPhone since the issue began? These are simple first steps that often help.

Meanwhile, here are some step-by-step things we can try to fix the crash:

1. Force Close and Reopen the App:
- Swipe up from the bottom of your screen and hold to bring up the app switcher.
- Find Test'em All and swipe it up to close it completely.
- Then open the app again.

2. Restart Your iPhone:
- Press and hold the side button with a volume button until the power off slider appears.
- Drag the slider to turn off.
- After your device powers down, press and hold the side button to restart.

3. Check for App Update:
- Open the App Store, tap your profile picture, scroll to see if Test'em All has an update available, and install it if so.

4. Delete and Reinstall the App:
- Sometimes app data can get corrupted. Long-press the app icon, tap “Remove App,” and then delete it.
- Re-download it from the App Store.
- This won’t delete your account info if it’s stored on the cloud, but let me know if you want to be cautious.

5. Check Storage Space:
- Go to Settings > General > iPhone Storage and see if you're low on free space (below 1 GB). Low storage can cause crashes.

6. Look for iOS Updates:
- Apple often releases fixes for stability. Go to Settings > General > Software Update to see if there’s a newer iOS version.

If you've already tried some of these, please tell me which ones, and whether you noticed any error messages before the app closes. Also, does this happen instantly or after a few seconds? With that info, we can dive deeper.

From what I’ve seen, crashes on Test’em All app can sometimes be related to account problems too; if you’re signed into a test account or beta version, that could cause a conflict.

Let me know how these go, and we’ll get your app cooperating again!
Are you satisfied with this plan so far?
