Hi there! I'm Pierre, and I'm here to help you with the Sam's Club app issues you're experiencing. It sounds like the app crashing is causing some trouble, especially when you're trying to reset your password. Let’s work through this together.

1. Check for Updates: First, let’s make sure that your iPhone and the Sam’s Club app are updated. Sometimes, app crashes can occur if you're not running the latest version. Go to the App Store, tap on your profile icon at the top right, and scroll down to see if there are any available updates for the Sam’s Club app.

2. Restart Your iPhone: Sometimes, a simple restart can solve app issues. Hold the power button and either volume button until the slider appears, then slide to turn off. After it powers down, turn it back on.

3. Reinstall the App: If it’s still crashing, try uninstalling and reinstalling the app. You can do this by tapping and holding the app icon until you see the option to remove it. Once it's uninstalled, head back to the App Store to download it again.

4. Clear App Cache: Though iOS handles app caches differently, reinstalling the app can act similarly. It ensures you’re starting fresh without old data that may be corrupted.

5. Password Reset: If you still need to reset your password, you can do so through the Sam’s Club website. Visit the Forgot Password page and follow the steps to reset your password if the app isn't cooperating.

6. Adjust Your Settings: Sometimes, settings can affect app performance. Check if you have sufficient storage on your iPhone and if necessary, free up some space by deleting unused apps or files.

If these steps don't resolve the issue, it might be worth checking the Sam’s Club support page for more specific troubleshooting steps related to app crashes here.
