Simple code does not run on the Android 12 device

Processing for Android
1

Hello.
I installed Processing 4.2
And I changed my phone (android 12) to usb debugging mode and connected to PC.
After then, I checked my Android device in the Android device menu and the tutorial simple sketch successfully installed on the device.
But the simple code does not run on the device Android 12 version(LG- V50). It runs on the device Android 10(LG-V40) in the same way.
What do I need to do more to make it run in version 12?

void setup() {
  fullScreen();
  noStroke();
  fill(0);
}

void draw() {
  background(204);
  if (mousePressed) {
    if (mouseX < width/2) {
      rect(0, 0, width/2, height); // Left
    } else {
      rect(width/2, 0, width/2, height); // Right
    }
  }
}

===============================
this is the message in console

If you don’t include import statements it is quite impossible to say what is wrong in you code. But I have to say that I found Processing first time yesterday, so I am not expert of Processing with Android.

Perhaps a package is incompatible.

Appears to be same problem described here: https://github.com/processing/processing-android/issues/729#issuecomment-1578967148
