Hi there! I see you're having trouble with the Casey's app crashing during login and not allowing you to get the passcode to sign in. That definitely makes it hard to use the app, so let's get to the bottom of it.

Just to help me better understand:
- Are you trying to receive the passcode via email or text message?
- Have you noticed if the app crashes immediately after entering the passcode, or before you get a chance to enter it?
- Have you already tried restarting your device or reinstalling the app?

Meanwhile, here are some general steps that often help with these kinds of issues on Windows systems or apps running through mobile devices:

1. Check your Internet Connection: Make sure you have a stable internet connection. Sometimes spotty connections can interfere with receiving passcodes or cause app crashes.

2. Update the app: Ensure the Casey’s app is updated to its latest version. Older versions may have bugs fixed in newer releases.

3. Clear Cache (if applicable): If you are running this app on an emulator or Windows subsystem that supports it, clearing app cache or temporary files might help remove corrupted data causing crashes.

4. Restart your device: This simple step can clear up temporary glitches.

5. Uninstall and Reinstall the app: This can reset the app to factory defaults and fix corrupted installations that cause login failures or crashes.

If none of these solves your issue, there could be a temporary outage or app-wide issue based on recent reports from others having login code problems and crashes after entering their login details1 2.

Let me know the details I asked, and based on that I can guide you through more specific troubleshooting or next steps!
