Get error when running Add-Migration in EF Core code-first

I search internet a lot and ask question form chatgpt a lot, too, but I can't find my answer. I got error when I run add-migration:

> The property 'quizType' cannot be removed from entity type 'DataLayer.Models.QuizModel (Dictionary<string, object>)' because it is being used in the foreign key {'quizType'} on 'DataLayer.Models.QuizModel (Dictionary<string, object>)'. All containing foreign keys must be removed or redefined before the property can be removed.

But I don't removed anything I think the error is wrong this is my quiz context and my model:

namespace DataLayer.Models
{ 
    public class QuizType
    {
        [Key]
        [Required]
        public int quizType { get; set; }

        [MaxLength(150)]
        public string QuizTitle { get; set; }

        public QuizModel quizModel { get; set; }
    }
}

UserModel:

namespace DataLayer.Models
{
    public class UserModel
    {
        [Key]
        [Required]
        public int UserID { get; set; }

        [Required]
        [MaxLength(300)]
        public string UserName { get; set; }

        [Required]
        [MaxLength(300)]
        public string Password { get; set; }

        [AllowNull]
        [MaxLength(150)]
        public string Role { get; set; }

        public ICollection<QuizModel> quizes { get; set; }
    }
}

QuizModel:

namespace DataLayer.Models
{
    public class QuizModel
    {
        [Key]
        [Required]
        public int QuizID { get; set; }

        [Required]
        [MaxLength(150)]
        public string QuizName { get; set; }

        [MaxLength(300)]
        public string Categories { get; set; }

        [Required]
        public int QuestionCount { get; set; }

        [Required]
        public int QuizType { get; set; }

        [ForeignKey("QuizType")]
        public QuizType quizType { get; set; }

        [Required]
        [ForeignKey("User")]
        public int UserID { get; set; }

        public UserModel User { get; set; }

        public ICollection<QuestionModel> Questions { get; set; }
    }
}

QuestionModel:

namespace DataLayer.Models
{
    public class QuestionModel
    {
        [Key]
        [Required]
        public int QuestionID { get; set; }

        [Required]
        [MaxLength(400)]
        public string QuestionText { get; set; }

        [Required]
        public int QuizType{ get; set; }

        [ForeignKey(name:"quiz")]
        public int QuizID { get; set; }

        public QuizModel quiz { get; set; } 

        public AnswerModel Answer { get; set; }

        public ICollection<AnswerOption> Oprtions { get; set; }
    }
}

AnswerModel and AnswerOption classes:

namespace DataLayer.Models
{
    public class AnswerModel
    {
        [Key]
        [Required]
        public int AnswerID { get; set; }

        [Required]
        [MaxLength(300)]
        public string Answertxt { get; set; }

        [Required]
        [ForeignKey(name: "Question")]
        public int QuestionID { get; set; }

        public QuestionModel Question { get; set; }

        [Required]
        public bool AnswerValidation { get; set; }
    }

    public class AnswerOption
    {
        [Key]
        [Required]
        public int OptionID { get; set; }

        [Required]
        [MaxLength(300)]
        public string Optiontxt { get; set; }

        [Required]
        public bool answerValidation { get; set; }

        [Required]
        [ForeignKey(name: "questionModel")]
        public int QuestionID { get; set; }

        public QuestionModel questionModel { get; set; }
    }
}

You are doing wrong name for "QuizType" class Primary Key instead of just "quizType" you should do "QuizTypeID" or "ID" and this will resolve the issue.
