Could not acquire lock on uia2_device_port_guard. File already exists

I am new in Appium. I run my app from last 3 weeks by using this code. suddenly when I run this from another class it shows this error in appium server. I do know why it's occurring. I run it in the morning.

public class BaseClass {

public AndroidDriver<AndroidElement>  driver;

@BeforeClass
public  AndroidDriver<AndroidElement> capabilities() throws MalformedURLException{

    File appDir = new File("src/test/resources");
    File app = new File(appDir, "KandareeLiteApp.apk");
    
    DesiredCapabilities capabilities = new DesiredCapabilities();

    capabilities.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, "100");
    capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, MobilePlatform.ANDROID);
    capabilities.setCapability(MobileCapabilityType.DEVICE_NAME, "emulator-5554");
    capabilities.setCapability(MobileCapabilityType.APP, app.getAbsolutePath());
    
    capabilities.setCapability("appPackage", "bd.com.cslsoft.kandareeliteapp");

    capabilities.setCapability("appActivity","bd.com.cslsoft.kandareeliteapp.view.activities.LauncherActivity");
    driver = new AndroidDriver<AndroidElement>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
    driver.resetApp();
}

Here is the Appium server-side code-- when start [Logcat] it take so much time.
