When i transition into another view, it doesn't stay there but rather shows up and disappears

Here is the code. I am meant to for from RegistrationView to the ProfilePhotoSelectorView(), but it shows up then disappears.

import SwiftUI
import Firebase


class AuthViewModel: ObservableObject {
    
    @Published var userSession: FirebaseAuth.User?
    @Published var didAuthenticateUser = false
    
    init() {
        self.userSession = Auth.auth().currentUser
        print("Debug: User session is \(self.userSession?.uid)")
    }
    
    func login(withEmail email: String, password: String){

        Auth.auth().signIn(withEmail: email, password: password) { result, error in
            if let error = error {
                print("Debug: Failed to sign in with error \(error.localizedDescription)")
                return
            }
            guard let user = result?.user else {return}
            self.userSession = user
            
            print("Debug: Did log user in")
        }
    }
    
    func register(withEmail email: String, password: String, fullname: String, username: String){
        
        Auth.auth().createUser(withEmail: email, password: password) { result, error in
            if let error = error {
                print("Debug: Failed to register with error \(error.localizedDescription)")
                return
            }
            
            guard let user = result?.user else {return}

            print("Debug: Registered user successfully")
            print("Debug: User is \(self.userSession)")
            let data = [
            
                "email" : email,
                "username" : username.lowercased(),
                "fullname" : fullname,
                "uid" : user.uid
                
            ]
             
            Firestore.firestore().collection("users")
                .document(user.uid)
                .setData(data){ _ in
                    self.didAuthenticateUser = true

                }
        }

    }
    
    func signOut() {
        userSession = nil
        try? Auth.auth().signOut()
    }
}

This all looks right, do you have anywhere else where you’re calling this variable didAuthenticateUser??
