Dell Inspiron 14 Plus 7420 2-in-1 freezes during initial setup

I recently purchased a new laptop (detailed above), and it started up like normal. I set up my keyboard, my region, the language, the wifi, etc etc. I logged in to windows just fine. When I tried to set up my Windows HELLO pin, it was initially rejected, and I had the option to "retry" or "skip for now." From here, the laptop screen froze, retry button activated mid-way. The cursor works just fine, but the screen won't respond to keyboard input or the touchscreen. It's brand new, and I'm not sure how to turn it off or restart, or if I even can since the keyboard is unresponsive and I haven't even made it past the set up. What should I do?
