Hi there! I'm sorry to hear that you're experiencing issues with the Expensify iOS app crashing on startup. That can be really frustrating! Let's work through this together.

First, I’ll need a bit more information. Can you let me know if you’ve tried anything so far to fix the issue, like restarting the app or your device?

In the meantime, here are some common steps that might help resolve the crashing issue:

1. Force Close the App: Sometimes, simply force-closing the app can resolve temporary glitches. You can do this by swiping up from the bottom of the screen (or double-tapping the home button) to view your open apps, then swipe up on Expensify to close it.

2. Restart Your Device: If you haven't done this yet, try restarting your iPhone. This can clear up any system issues that might be causing the crash.

3. Check for Updates: Make sure your Expensify app is updated to the latest version. Go to the App Store, tap on your profile icon, and scroll down to see if an update is available.

4. Reinstall the App: If the steps above don’t work, consider uninstalling and then reinstalling the app. Tap and hold the Expensify app icon, select "Remove App," then go to the App Store to download it again.

5. Clear App Cache (if possible): Some devices allow you to clear cache without uninstalling. You might want to check your settings for any options related to clearing storage or cache.

If you’ve already tried any of these steps, let me know, and we can move to some more advanced troubleshooting techniques.
