Class object property model is null?

I am building a to-do-list project as a practice. It has one relationship to the Member model and the Member model has many relationships to 'to-do-list'

Member controller create method works without any issue but the to-do-list controller throws model state is invalid on Member object property of to-do-list

ToDoList

using System.ComponentModel.DataAnnotations;

namespace To_Do_List.Models
{
    public class ToDoList
    {
        [Key]
        public int Id { get; set; }

        [Required]
        [StringLength(200, MinimumLength = 1, ErrorMessage = "To Do List Item cannot be longer than 200 characters.")]
        public string Title { get; set; }
        public string Description { get; set; }

        [DataType(DataType.Date)]
        public DateTime DueDate { get; set; }


        public string Priority { get; set; }
       
        public int AssignToId { get; set; }

        
        public Member AssignTo { get; set; }
        [Required]
        [StringLength(15, ErrorMessage = "The {0} must be at least {2} and at max {1} characters long.")]
        [RegularExpression("^(Completed|Not Completed)$", ErrorMessage = "The status must be Completed or Not Completed")]
        public string Status { get; set; }
        
    }
}

Member

using Microsoft.Build.Framework;

namespace To_Do_List.Models
{
    public class Member
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Email { get; set; }

        [Required]
        public ICollection<ToDoList> ToDoLists { get; set; }
        
        
    }
}

create method of to do list controller

  public async Task<IActionResult> Create([Bind("Id,Title,Description,DueDate,Priority,AssignToId,AssignTo, Status")] ToDoList toDoList)
  {
            


            if (ModelState.IsValid)
            {
                _context.Add(toDoList);
                await _context.SaveChangesAsync();
                return RedirectToAction(nameof(Index));
            }

            ViewData["AssignToId"] = new SelectList(_context.Members, "Id", "Id", toDoList.AssignToId);
            return View(toDoList);
  }

View method of to do list

public IActionResult Create()
        {
            return View();
        }

Create.cshtml

@model To_Do_List.Models.ToDoList

@{
    ViewData["Title"] = "Create";
}
