TestRunner returning NPE when running as TestNG Test

Question

I'm practicing some automation with Java + Cucumber + TestNG. I programmed a initialSetup class with all the of the WebDriverManager basic configuration I want to use. If I run a Cucumber Feature directly from the Feature File it works fine, but if I run the feature from the TestRunner class (TestNG) it fails, returning NullPointerException and saying that the driver equals null.

What could be wrong or what could I do?

initialSetup class where the WebDriverManager is set up:

package setup;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.BeforeTest;
import io.github.bonigarcia.wdm.WebDriverManager;
public class initialSetup {
    
    
    private static WebDriver driver;
    
    @BeforeTest
    public static void setupClass() {
        WebDriverManager.chromedriver().setup();
        driver = new ChromeDriver();
        setDriver(driver);  
    }
    
    public static void setDriver(WebDriver driverValue) {
        driver = driverValue;
    }
    
    public static WebDriver getDriver() {
        
        return driver;
    }

}

Here is my TestRunner class, in which the setup of TestNG i:

package Runner;

import io.cucumber.testng.AbstractTestNGCucumberTests;
import io.cucumber.testng.CucumberOptions;


//@RunWith(Cucumber.class)
@CucumberOptions(
        features = "src/test/java/features/",
        glue= {"stepDefinition"},
        plugin = { "pretty" },
        monochrome = true
        )
 
public class TestRunner extends AbstractTestNGCucumberTests {
    
}

And just in case is needed, here is my pom.xml
