SEVERE: Unable to kill process Process[pid=25680, exitValue=1]

Issue is seen only in headless mode.

Driver class :

if (browserType.equalsIgnoreCase("chrome")) {
            ChromeOptions options = new ChromeOptions();
            options.addArguments("--headless");
            options.addArguments("--disable-gpu");
            options.addArguments("--no-sandbox");
            options.addArguments("--window-size=1920,1080");
            options.addArguments("--disable-extensions");
            options.addArguments("--proxy-server='direct://'");
            options.addArguments("--proxy-bypass-list=*");
            options.addArguments("--start-maximized");
            options.addArguments("--ignore-certificate-errors");
            WebDriverManager.chromedriver().setup();
            driver = new ChromeDriver(options);
            DriverManager.setDriver(driver);
            System.out.println("Chrome Browser Launched !!!");

@AfterMethod(alwaysRun = true)
protected void afterMethod(ITestResult result) throws Throwable {
    if (result.getStatus() == ITestResult.SKIP) {
        ExtentReport.removeTest();
    }
    ExtentReport.flushReports();
    Driver.quitDriver();
}
