Picker stops working when @Environment is added to the View

I have a Form on my View containing couple of Pickers.

Picker stops working when @Environment(\.presentationMode) var presentationMode is added to a View.

struct NewOperationView: View {
    @Environment(\.presentationMode) var presentationMode
    @State var docDate: Date

    @State var doctorID: Int64
    @State var doctors: [listStruct] = []

    @State var refOperationID: Int64
    @State var refOperations: [listStruct] = []

    @State var productsList: [productListStruct] = []

    let df: DateFormatter = DateFormatter()
    let barcodeService = BarcodeService()

    var body: some View {
        VStack {
            Form {
                HStack {
                  Text("Date")
                  Spacer()
                  Text(df.string(from: docDate))
                }
                Picker("Doctor", selection: $doctorID) {
                    ForEach(doctors) { doctor in
                        Text(doctor.title).tag(doctor.id)
                    }
                }
                Picker("Operation", selection: $refOperationID) {
                    ForEach(refOperations) { refOperation in
                        Text(refOperation.title).tag(refOperation.id)
                    }
                }
                Section("Prothesis") {
                    List {
                        ForEach(productsList) { product in
                            ProductRow(product: product)
                        }.onDelete(perform: delete)
                    }
                }
            }
        }
    }
}

Before importing the @Environment all works well, Picker's value is displayed, and selectable. But After importing pickers turns empty, and selecting the value in picker does not change the value of the picker
