Blazor StateObject lost after Navigation to next page

Blazor Server
Blazor Web App
InteractiveServer
.NET 8

builder.Services.AddScoped<NavParams>();

Working Normally:
I have a Blazor Web App with 20 pages.
I use NavParams as a statebag that is injected into each page.
I use NavigationManager.NavigateTo("myNextPage") in all page navigation.
This navigation is initiated by a mouse click on a link or button.
Everything works fine.

Not Working:
I have introduced Authentication.
The home page has
@attribute [Authorize]
Upon successful authentication I navigate to the next page but the NavParams.Hotel is null.
The difference is I an not initiating the navigation with a click event.

protected async override Task OnInitializedAsync(){    NavParams.Hotel = new Hotel();    NavigationManager.NavigateTo(HotelRoutes.Details, forceLoad: false);}

In the target page, HotelDetails, I load the NavParams object and gather the Hotel object

protected async override Task OnParametersSetAsync(){        Hotel = NavParams.Hotel;        //Hotel is null }

Hotel is NULL
