Apple Sign In Not Returning

I am having trouble with one of my apps that will not let me log in via Apple Sign In. I am using Firebase and Firebase UI for the sign in process. I have many other apps with the same exact config that currently work just fine, but this one I have gone as far as completely deleting the targets and rebuilding and it will not return from the login screen

I checked the following:

Sign in with Apple ID Capability is available in XCode and on the dev certificate on developer.apple.com I have also toggled both of them on and off.

I have double checked the config in Firebase to turn on the Apple Login identifier. Again I have toggle it on and off.

I have cleaned the project multiple times to no avail.

I have logged out and back into my developer account in XCode.

It seams like after I put in the correct password to log in, it just never returns to the app, there is no logging. I do get a notified(shaking input box) if I put in an incorrect password, but when I put in the correct one, the login window never dismisses and my app is not notified.

I checked the Console and the last message from akd on a working app is: Notifying client (bundle) of credential state change 1. Remote view sent a finish event

On the one not working, using the same user and password akd returns: SRP authentication with server failed! Error: Error Domain=com.apple.AppleIDAuthSupport Code=2 "M2 missing (bad password)

I have 100% verified I am putting in the correct user password. I was only notified of this issue because Policy is having the same issue logging in during App Review. Also, if I put in a bad password the input window shakes and when this is happening, the input window is not shaking
