Newbie - need help with companion app

Hello, I am new to home assistant and I am struggling to get the companion app to connect on a fresh set up. I have HA running on a Home Assistant Green, and have been able to connect and log-in on my desktop no problem. On my iPhone 17 the companion app is able to detect my HA, but when I enter my log in credentials the app crashes immediately.

I have tried clearing and reinstalling the companion app, power cycling the HA Green device, updating my iOS, and nothing has changed. Could really use some help troubleshooting this as I'm new and really don't even know where to start.
