Program crashing when initializing variables - ExtentReports 5.1.2

[J-Kiri]

so i'm trying to apply ExtentReports on a java selenium test application

@TestMethodOrder(MethodOrderer.OrderAnnotation.class)
public class AvantewebsuiteTest {
. . .

 private static ExtentReports extent;
 private static ExtentTest test;

 static{
 try{
 System.out.println("Init Spark");
 ExtentSparkReporter spark = new ExtentSparkReporter("reports/AvanteWebSuiteReport.html");
 System.out.println("Inited Spark");

 spark.config().setReportName("Avante Web Suite - Test Report");
 spark.config().setDocumentTitle("Relatório de Testes");

 System.out.println("Init Extent");
 extent = new ExtentReports();
 System.out.println("Inited Extent");
 extent.attachReporter(spark);

 extent.setSystemInfo("Projeto", "AvanteWebSuite");
 extent.setSystemInfo("Ambiente", "QA");
 extent.setSystemInfo("Usuário", System.getProperty("user.name"));

 } catch (Exception e) {
 e.printStackTrace();
 throw new ExceptionInInitializerError("Failed to initialize ExtentReports: " + e.getMessage());
 }
 }

 public static ExtentReports getExtentReports() {
 return extent;
 }
. . .

The problem is, the program executes that first sout System.out.println("Init Spark"); but as soon as it touches the ExtentSparkReporter spark = new ExtentSparkReporter("reports/AvanteWebSuiteReport.html"); line it gives me this error:

My mave dependencies are all okay, no conflicts or anything. if i run a minimal setup in the same enviroment like:

package testes.avante.testes;

import com.aventstack.extentreports.ExtentReports;
import com.aventstack.extentreports.reporter.ExtentSparkReporter;

public class ExtentSpark {
 public static void main(String[] args) {
 try {
 System.out.println("Initializing ExtentSparkReporter...");
 ExtentSparkReporter spark = new ExtentSparkReporter("test-report.html");
 System.out.println("ExtentSparkReporter initialized successfully!");

 ExtentReports extent = new ExtentReports();
 extent.attachReporter(spark);

 extent.createTest("Sample Test").pass("This test passed!");
 extent.flush();

 System.out.println("Report generated successfully.");
 } catch (Exception e) {
 e.printStackTrace();
 }
 }
}

everything works perfectly!

i really dont know what to do anymore. if anyone knows what to do, i appreciate the help
