You can force quit an app on the Apple Vision Pro just as you can on the Mac, iPhone, and iPad. An Apple support doc explains how:
° Simultaneously press and hold the Digital Crown and top button until you see Force Quit Applications.
° Be sure to release the Digital Crown and top button after you see Force Quit Applications, as holding them for too long can force restart Apple Vision Pro.
° Tap the name of the app you want to close, then tap Force Quit.
