The cursor isn’t clicking on my Dell XPS. The touchpad works and so the cursor moves across the page, but I can’t select or click on anything. Also, I can’t log into my computer bc my camera won’t turn on for

face recognition and I can’t alternatively enter my password bc I can’t click into the password box. I can’t click on the on/off icon at the bottom of the screen to reboot my computer. Any thoughts? I’m completely stumped. Thanks!!!
