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

For anyone else having this issue, you have to just wait it out. After 11 days it just worked.
