Hi there! I’m sorry to hear that the app is crashing when you try to log in. Let’s work this out together.

First, could you let me know if you've tried any troubleshooting steps already? For example, have you restarted your iPhone or updated the Chili's app to the latest version? These simple steps can sometimes resolve issues like this.

If not, here's what we can try:

1. Restart Your iPhone: Press and hold the power button, then slide to power off. After it's off, turn it back on and try logging in again.

2. Update the App: Open the App Store, tap on your profile icon at the top right, and scroll down to check if there are any updates available for the Chili's app.

3. Clear App Cache: Go to Settings > General > iPhone Storage. Find the Chili's app and tap on it. If there's an option to offload the app, select that. After it's done, reinstall the app from the App Store.

4. Check for iOS Updates: Navigate to Settings > General > Software Update to ensure your iOS is up-to-date.

If you've done these already or if the issue persists, please let me know, and we can explore more advanced troubleshooting steps!
