Error on second tab alert Presenting view controller <SwiftUI.PlatformAlertController: > 0x10580c400> from detached view controller

Is this a wrong usage of the concept of "error manager"? Is it something in SwiftUI that is not used anymore? On second tab, when I try to show error, on console I get this:

Presenting view controller <SwiftUI.PlatformAlertController: 0x10580c400> from detached view controller <TtGC7SwiftUI19UIHostingControllerVS_14_ViewList_View: 0x10385ee00> is not supported, and may result in incorrect safe area insets and a corrupt root presentation. Make sure <TtGC7SwiftUI19UIHostingControllerVS_14_ViewList_View: 0x10385ee00> is in the view controller hierarchy before presenting from it. Will become a hard exception in a future release.

    static let shared = ErrorManager()

    func handleError(_ error: TestError) {
        self.currentError = error
    }
}

enum TestError: Error, Identifiable, LocalizedError {
    var id: String {localizedDescription}
    
    case genericError
    
    var errorDescription: String? {
        switch self {
        case .genericError:
            return "Generic Error"
        }
    }

Put the alert on the TabView or even ContentView not the FirstView.
