Request quits unresponsive when trying to assign value to a string using Dapper

I'm using Dapper to make queries in my database. And in one of those queries I have a result that I was not expecting, and without any error message.

What happens is that I am making a request request from Postman, and this request reaches my WebAPI, but I do not get a response and the request closes.

Debugging the code I got into the method where I do the SQL query using Dapper, and when trying to assign value to the string field the application simply gives dispose in all classes without displaying error messages.

Below is my code:

private async Task<ClassificacaoRiscoModelRequest> ObterClassificacaoRisco(string protocolo)
    {
        string query = $@"SELECT

The template class I am using to extract the information is drawn as follows:

public class ClassificacaoRiscoModelRequest : BaseModelRequest
{

    public string NomeEspecialidade { get; set; }
    public string NomeCausaExterna { get; set; }
    public DateTime DataCriacao { get; set; }

    //Conteudo Classificação
    public bool EscalaGlasgow { get; set; }
    public bool TemNefropatia { get; set; }
    public bool TemOutrasDoencas { get; set; }
    public bool TemDiabetesPaciente { get; set; }
    public bool TemDoencaRespiratoria { get; set; }
    public bool TemCardiopatiaPaciente { get; set; }
    public bool TemHipertensaoPaciente { get; set; }
    public bool MedicamentoEmUsoPaciente { get; set; }

    public string CboDesc { get; set; }
    public string Neoplasia { get; set; }
    public string OutrasDoencas { get; set; }
    public string AberturaOcular { get; set; }
    public string OutrosDetalhes { get; set; }
    public string QueixaPaciente { get; set; }
    public string RespostaMotora { get; set; }
    public string RespostaVerbal { get; set; }
    public string ResultadoEscalaComa { get; set; }
    public string CorClassificacaoRisco { get; set; }
    public string EscalaGlasgowJustificativa { get; set; }
    public string MedicamentoEmUsoPacienteDetalhes { get; set; }

    //Conteudo Usuário
    public string Cpf { get; set; }
    public string Nome { get; set; }

    //Conteudo Avaliação
    public string Htg { get; set; }
    public string Sato { get; set; }
    public string Pulso { get; set; }
    public bool Alergia { get; set; }
    public string PressaoArt { get; set; }
    public string Temperatura { get; set; }
    public string PesoAproximado { get; set; }
    public string AlergiaDetalhes { get; set; }
}

Exactly when it arrives in the SET method of the property "CorClassificacaoRisco" the application simply exits from debug mode and I get no response from my request.

If anyone knows what it is or has already experienced this problem, please introduce me to the solution.
