iOS widget crashing in body getter with -[NSTaggedPointerString identifier]: unrecognized selector sent to instance

Here is the code where the crash occurs

var body: some WidgetConfiguration {
        IntentConfiguration(kind: WidgetKind, intent: ConfigurationIntent.self, provider: provider) { entry in
            // Parse config
            if let config = entry.configuration {
                if let fg = config.foreground,
                   let fgColorId = fg.identifier, <----
                   let fgColors = AppSettings.sharedInstance()?.object(forKey: kWidgetForeground) as? [String:String],
                   let fgColor = fgColors[fgColorId] {
                    theme.textColor = Color.init(UIColor.fromHex(fgColor))
                    theme.iconColor = Color.init(UIColor.fromHex(fgColor))
                } else {
                    theme.textColor = .white//Color.primary
                    theme.iconColor = .white//Color.primary
                }

configuration is INIntent with foreground var which is INObject but some times it seems its not... and instead its NSTaggedPointerString unless I'm missing something here.
