Hello,
Welcome to our Microsoft Q&A platform!

The index of the previousPage in the NavigationStack is not FirstOrDefault(), stack follows the LIFO (Last In First Out) principle. So, its index is NavigationStack.Count - 2. You could also use the name of page to find which page you want to remove, refer to the following code:

private void Button_Clicked(object sender, EventArgs e)  
        {  
         //var previousPage = Navigation.NavigationStack.OfType<FirstPage>()?.FirstOrDefault();  
        //Navigation.RemovePage(previousPage);  
        //this.Navigation.PopAsync();  

            this.Navigation.RemovePage(this.Navigation.NavigationStack[this.Navigation.NavigationStack.Count - 2]);  
            this.Navigation.PopAsync();  
        }  

In fact, FirstPage has been removed, however, we need pop the current page to check the effect.
