Steps & Code to Reproduce

func configureFlexibleSync() async throws -> Realm { print("Starting configureFlexibleSync function...")

// Ensure the current user exists
guard let user = app.currentUser else {
    print("No logged-in user found.")
    throw NSError(domain: "Login Error", code: 401, userInfo: [NSLocalizedDescriptionKey: "No logged-in user found."])
}

print("Current user: \(user)")

let config = user.flexibleSyncConfiguration()
print("Flexible sync configuration created.")

// Open Realm asynchronously
let realm = try await Realm(configuration: config)
print("Realm opened successfully.")

// Safely unwrap the email property outside of the subscription update block
guard let userEmail = user.profile.email else {
    print("User profile email not found.")
    throw NSError(domain: "Profile Error", code: 402, userInfo: [NSLocalizedDescriptionKey: "User profile email not found."])
}
print("User email: \(userEmail)")

// Update subscriptions without removal to avoid potential issues
try await realm.subscriptions.update {
    print("Updating subscriptions...")

    // Check if a subscription for UserProfile already exists
    if let existingSubscription = realm.subscriptions.first(named: "UserProfile") {
        print("Existing subscription for UserProfile found.")
    } else {
        print("No existing subscription found for UserProfile. Adding new subscription for user: \(userEmail)")
        // Add a new subscription for the UserProfile filtered by email
        realm.subscriptions.append(QuerySubscription<UserProfile>(name: "UserProfile") {
            $0.email == userEmail
        })
    }
}

print("Subscriptions updated successfully.")

// Return the Realm instance after the subscriptions are updated
return realm
