JavaFX error "Caused by: java.lang.IllegalAccessError: (...)"

Question

I got this error when trying to run a program of mine, cannot access class com.sun.javafx.beans.IDProperty and goes

I've tried to google every error I could think of, and none of them worked, even here in stackoverflow I didn't found anything that could help me, that's why I'm asking a specific one

I believe the error is in this class, because it started to happen since I created it.

package controller;

import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import principal.Main;

public class perfilTeste {
    Main tela = new Main();

    @FXML
    protected void btnVoltar(ActionEvent evento){
        System.out.println("Voltar - PERFIL");
        tela.mudaTela(2);
    }

    @FXML
    protected void btnSair(ActionEvent evento){
        System.out.println("Sair");
        tela.mudaTela(0);
    }

    @FXML
    protected void btnLimpar(ActionEvent evento){
        System.out.println("Limpar");

    }

    @FXML
    protected void btnEnviar(ActionEvent evento){
        System.out.println("Limpar");

    }
}

This is the error that shows up when I try to run the program
