Accesing modelContext Outside of View Hiearchy Causing modelContext to not Save

Im running into an issue where swiftdata works perfectly and saves my data if I comment out any lines that call performSync but as soon as I try to call performSync(), SwiftData fails to save any changes whatsoever. I pass in modelContext into the custom class from the @Enviroment operator from a view onAppear. How do I fix this?

func performSync() async {
        guard let notionService = notionService, isInitialized else { return }
        
        // Set isSyncing on the main actor.
        await MainActor.run {
            isSyncing = true
        }
        
        do {
            // Fetch the ideas on the main actor.
            let ideas: [Idea] = try await MainActor.run {
                let descriptor = FetchDescriptor<Idea>()
                return try modelContext.fetch(descriptor)
            }
            
            try await notionService.syncIdeas(ideas)
            
            // Save changes on the main actor.
            await MainActor.run {
                try? modelContext.save()
                isSyncing = false
            }
        } catch {
            print("Sync failed: \(error)")
            await MainActor.run {
                isSyncing = false
            }
        }
    }

.onAppear{
 if let paId = UserDefaults.standard.string(forKey: DefaultsKeys.parentPageId){
   if !completedSetupSync{
     authManager.setupSyncManager(parentPageId: paId, modelContext: modelContext)
     completedSetupSync = true
        }
    }
}

I was expecting the code to not effect other container changes outside the class and also be able to save changes to the context itself.
