Help: Connect your Mac to the monitor and press the keyboard to jump back to the desktop

Machine : MBP M3 PRO System: 15.4.1 Situation: Connect an external monitor. The external monitor screens an application (such as Android studio), and the built-in monitor screens an application (such as Chrome). At this time, press Enter and other buttons in Android studio, and the built-in monitor will jump back to the desktop. At first, I thought I touched the touchpad by mistake, but I tried it and found that sometimes just pressing the keyboard would jump from time to time. I don't know which setting caused it. Has anyone encountered this situation?
