Can someone explain why EF is failing here?

Message: System.InvalidOperationException: Cycle detected while auto-including navigations: ‘CatalogPage.Pages’. To fix this issue, either don’t configure at least one navigation in the cycle as auto included in OnModelCreating or call ‘IgnoreAutoInclude’ method on the query.

What?

Model:

public class CatalogPage
{
    [Key]
    public int Id { get; init; }
    public string? Name { get; init; }
    public string? Layout { get; init; }
    public int? RoleId { get; init; }
    public int CatalogPageId { get; init; }
    public int OrderId { get; init; }
    public int IconId { get; init; }
    public bool Enabled { get; init; }
    public bool Visible { get; init; }
    public ICollection<CatalogPage> Pages { get; init; } = [];
    public ICollection<CatalogItem> Items { get; init; } = [];
}

I am auto loading Pages…

When I try and fetch like so, it fails:

var parentlessPages = await dbContext.Set<CatalogPage>()
    .Where(x => x.CatalogPageId == -1)
    .ToListAsync();
