Hi there! I understand that Rappi keeps crashing while you’re waiting for an order, and I’m here to help you sort this out. Let’s try a few steps to resolve this issue quickly.

1. Force Quit the App:
- Click on the Apple logo in the top left corner of your screen, then select Force Quit…. Find Rappi in the list and click Force Quit.
- After that, try reopening the app.

2. Update the App:
- Head to the App Store and check for any pending updates for Rappi. Sometimes, running an outdated version can cause crashes. If an update is available, go ahead and apply it.

3. Clear Cache:
- You can clear the app cache by deleting the app and then reinstalling it. To do this, simply drag Rappi from your Applications folder to the Trash, and then download it again from the App Store.

4. Check Your Internet Connection:
- Ensure you have a stable internet connection, as a poor connection might cause the app to crash. Try switching from Wi-Fi to cellular data or vice versa to see if that helps.

5. Restart Your Mac:
- Sometimes a simple restart can fix software issues.

Could you let me know if you’ve tried any of these steps already? If the issue persists after trying these, we can look at some more advanced troubleshooting options.
