Why my car battery died again?

So my car (ionic 5 Hyundai) battery died and after the jump start (jump start was for about 2 minutes)I drove for 30+ minutes. It gave an error on my dashboard to check Virtual engine sound system. I turned off the car. And after 3 hours I went back to start the car and it gave a message to stop the car at safe side immediately because of low battery. And now my car battery is dead again lol no hazard lights, and no lights are working.

Since it is a rental car, I will return the car and get a different one. But why is it dead again?
