+## [Unreleased]
+
+### Fixed
+
+#### Notification Settings Screen Error
+- **Issue**: Opening the Notification Settings screen would display "Error loading settings" with a `PlatformException: Missing type parameter` error
+- **Cause**: The `flutter_local_notifications` plugin's internal cache (stored in SharedPreferences) became corrupted, containing notification data with missing required fields
+- **Solution**: Added error handling in the notification service to gracefully catch and recover from corrupted notification cache errors
+- **Files Changed**:
+  - `lib/core/services/notification/notification_service.dart` - Added try-catch around `cancelNotification()` and `cancelAllNotifications()` methods
+  - `lib/features/notifications/presentation/state/notification_settings_controller.dart` - Added error handling in `_applySettings()` to prevent settings load failures
+
+**Workaround for existing users**: If you still experience issues after updating, clear the app data from your device settings (Settings > Apps > Keep Track > Storage > Clear Data). This will reset the corrupted notification cache.
